00:00 Dreaming is ridiculous. For reference,

00:03 we know more about the abyss that is the

00:05 Mariana's Trench than we do about the

00:07 mental landscapes of your dreams. We

00:09 know more about the tiny remnants of DNA

00:11 extinct creatures have left behind than

00:13 we do about your nightly hallucinations.

00:16 Heck, we even know more about Martian

00:18 dust storms than we do about our little

00:20 bedtime stories. And yet, everyone

00:22 dreams. They're the most private thing

00:24 that all of us have in common.

00:26 immediately recognizable but incredibly

00:29 difficult to define. So much so that for

00:32 decades dreams were believed to be

00:34 nothing more than brain noise. Very

00:36 fleeting and completely meaningless.

00:39 But if that's true, why would your brain

00:42 paralyze you during REM sleep? Why would

00:43 it burn costly energy running

00:45 simulations instead of repairing itself?

00:47 And why would REM sleep appear in the

00:49 womb way before any life experience? The

00:52 reality is the rabbit hole of dreams is

00:55 deep, way deeper than you think. And

00:57 from personal Reddit threads claiming to

00:59 see the same stranger in every dream for

01:01 over a decade to entire scientific

01:03 databases containing tens of thousands

01:05 of peer-reviewed dream reports,

01:07 completely different people find

01:09 themselves in the exact same places with

01:11 the exact same sequence of events,

01:13 sometimes even while being awake. So,

01:16 what exactly is going on here? And how

01:19 deep into dreams do we have to go to

01:20 find out? Well, as it turns out, dreams

01:23 have levels, and they get far stranger,

01:26 go far deeper, and are far more

01:28 consequential than we could have ever

01:31 possibly imagined.

01:35 Level one.

01:36 >> The five levels of dreams aren't random.

01:39 They build on one another through a

01:40 sequence. But before that sequence even

01:43 begins, there are two primary states of

01:45 consciousness that everyone will

01:46 experience. Being awake and being

01:49 asleep. However, what's less wellknown

01:51 is that there's also a third state, a

01:53 strange in between called hypnogogia,

01:56 which is a transitional state between

01:57 being awake then falling asleep or vice

02:00 versa. But what's interesting is that

02:03 even though you're not fully asleep, raw

02:06 fragmented noise still floods the brain,

02:08 specifically geometric patterns. And

02:10 yes, I mean these geometric patterns,

02:13 which in level one is the pulsating

02:15 chaos you'll experience as you drift

02:17 into sleep. It was Hinrich Clover in the

02:20 1920s who first documented this

02:21 phenomenon and he found that there were

02:23 four common patterns anytime someone

02:25 begins entering an altered state.

02:28 Latises, cobwebs, tunnels, and spirals,

02:32 all of which are described as the

02:34 precursors to our inner worlds. We're

02:36 not entirely sure why this happens, but

02:38 we do know it comes from the visual

02:40 cortex, which is one of the theories

02:42 behind why we dream in general. Because

02:44 of neuroplasticity, if the visual cortex

02:47 is unused, like in people who are blind,

02:49 neighboring brain regions essentially

02:51 invade that space to then repurpose it

02:54 for what they do. So, it's thought that

02:55 we dream as a defense mechanism to keep

02:58 the visual cortex active and protect its

03:00 territory while we sleep. But while this

03:03 may very well be why we started dreaming

03:05 in the first place, it doesn't explain

03:07 the content of dreams or why so many

03:09 brain areas other than the visual cortex

03:12 need to be involved. But still, these

03:14 geometric patterns are the doorway to

03:16 dreams. They're all that exist in level

03:18 one. Some people remember experiencing

03:20 them and some people don't. But it is

03:22 only once you cross through them that

03:24 the real dreaming begins.

03:27 >> Level two.

03:28 >> In level two, you're dreaming kind of.

03:31 You're somewhere. You might be someone,

03:33 but the dream is still forming. So, at

03:35 this level, the landscape is the focus,

03:37 but it's odd, feels incomplete, and is

03:40 completely empty. which is why this

03:43 level is where the concept of dreamscape

03:45 comes from. An art style defined by

03:47 surrealism, usually characterized by

03:49 familiar landscapes and bright colors.

03:51 But while most people focus on the

03:53 everyday environments, the houses that

03:55 look familiar, or the proportions that

03:57 make things feel off, what I find most

03:59 interesting is the things that are

04:01 missing. Now, I'm no artist, but I am

04:04 familiar with the concept of negative

04:06 spaces, which is when the absence of

04:08 something outlines the main subject of

04:10 the image by contrast. It works by

04:12 creating a visual hierarchy that guides

04:14 the viewer's eyes through the

04:16 composition. But where it really shines

04:18 is in its contribution to the harmony of

04:20 the art piece. Negative spaces are used

04:23 to distribute visual weight evenly.

04:25 However, artists can take advantage of

04:26 this by using too little or too much.

04:29 Use too little and you can alter the

04:31 viewer's perception by creating the

04:33 feeling of being overwhelmed. Use too

04:35 much and you can create a feeling of

04:37 isolation or emptiness. In Dreamscape,

04:40 aside from the fact that familiar

04:42 objects are often conveyed, images feel

04:45 familiar because the large negative

04:47 space gives you the room needed to

04:48 project your own feelings onto that

04:50 artwork. And in this level of dreams,

04:53 that's exactly what's happening. Dream

04:55 researchers describe it as the void

04:56 behind perception. Anthony Ravanchow

04:59 calls it selective simulation. Dream

05:01 dictionaries call it the archetypal

05:03 emblem of the void. Either way, this is

05:06 when your brain starts to build. And oh

05:08 boy, does it do that with the most vivid

05:10 accessible material it has at its

05:12 disposal. Memories. But not just any

05:15 memories. Heavy ones tagged with emotion

05:17 which come from the amygdala instead of

05:19 the hippocampus. But at this point,

05:21 what's supposed to be a dream is a void,

05:24 unrendered and empty. And yet, it is

05:26 that emptiness that allows the brain to

05:29 project its emotions onto that void,

05:31 creating a simple, barely rendered

05:33 landscape of emotion. Pure emotion in

05:36 its most primal, raw, and chaotic form

05:40 stitched together from the deepest parts

05:41 of your memories with no plot, no

05:44 structure, and no people bubbling up to

05:46 the surface as a foundation that every

05:49 other level will be built upon. However,

05:51 at this stage, what you experience is

05:54 just the beginning.

05:56 Level three.

05:57 >> A strange phenomenon that exemplifies

05:59 what level 3 is about is the airport

06:01 dream, which has hundreds of posts

06:03 dedicated to it on our dreams. In them,

06:06 people report finding themselves in an

06:08 airport, scrambling to catch a flight.

06:10 But as they make their way towards the

06:11 flight gate, things start to go terribly

06:13 wrong. At first, the gate will move or

06:16 disappear. In response, the dreamer

06:18 changes course, but as they do, they get

06:21 lost. So, in a desperate attempt at

06:23 reaching their flight on time, they try

06:25 to ask people for help, but get ignored

06:27 or worse, turn to find themselves as the

06:30 only person in a massive airport. And no

06:32 matter how much they run or how hard

06:34 they try, eventually they'll miss their

06:37 flight. Now, by itself, this isn't a

06:40 particularly unsettling dream. It's not

06:42 comfortable, obviously, but I wouldn't

06:44 call it a nightmare. However, where

06:46 things do start to get nightmarish is

06:48 when they repeat. And in the airport

06:50 dream, this seems to be a frequent

06:52 occurrence as a couple months later, the

06:54 same person will find themselves in the

06:56 same narrative arc, but happening on a

06:58 cruise or in a hotel or when they're on

07:00 vacation. All of which have the same

07:02 outcome, but with a different sequence

07:04 of events. Generally, it's thought that

07:07 a dream about never arriving in a

07:09 transportation setting is tied to

07:10 anxiety about unresolved life tasks. But

07:13 with the setting itself, depending on

07:14 the transportation settings you're most

07:16 accustomed to. Regardless, this

07:18 phenomenon perfectly encapsulates the

07:21 key aspect of this level. It's

07:23 metaphorical. With raw emotion taking

07:25 center stage, your brain is now trying

07:27 to shape it. But to do that, it needs to

07:30 turn up the volume, amplifying the

07:32 emotion until it's strong enough to be

07:34 processed. Without the ability to use

07:36 language, since you know you're asleep,

07:38 it does this by distilling the emotions

07:40 into one of five central themes.

07:42 identity, desire, fear, loss, or

07:46 conflict. Taking the same memory

07:48 fragments as earlier and then

07:50 repurposing and combining them into a

07:52 structure that can express one of these

07:54 themes. So, the plot that comes from

07:56 this isn't logical. It's not the story

07:58 you'd expect from a movie script. It's

08:01 emotional logic, cause and effect that's

08:03 used to reinforce the core emotion, not

08:06 to make literal sense. But why it

08:08 chooses these specific themes or where

08:10 those themes even come from is something

08:12 we still don't know. However, some

08:14 people have ventured far enough to give

08:16 us some clues.

08:18 Level four.

08:20 >> Level four is where dreams cross a

08:21 boundary. They stop feeling like they're

08:23 generated from you and start feeling

08:25 like they're generated for you.

08:27 Experiences include characters that keep

08:29 returning, real places you'll visit, and

08:32 encounters with independent agents. But

08:34 above all else, what defines this level

08:36 is the feeling that your experience is

08:38 in yours. And on Reddit, there's some

08:41 really strange examples of this. One

08:43 case describes the experience of

08:44 encountering the same figure night after

08:47 night across more than 10 years of

08:49 dreaming, first meeting as children, and

08:51 then growing up together. Another

08:53 describes dreaming about places they've

08:55 never been to or heard of. Vividly

08:57 picturing everything like the colors,

08:59 the architecture, or the extravagant

09:01 shop names, only to then wake up and

09:03 find out that that place and the way

09:06 they dreamt it actually exists. In both

09:08 cases, the dream unfolds from their

09:10 perspective, while the person in place

09:12 feel like independent agents. However,

09:15 these are individual examples. It's not

09:17 like this theme is that widespread,

09:19 right? Nope.

09:22 When I was looking through the massive

09:23 Dream Bank database, the most

09:25 interesting thing I found was this

09:28 consistent reports of being chased,

09:30 sometimes by strangers and sometimes by

09:32 people you know, sometimes on foot and

09:34 sometimes in a vehicle. Regardless, the

09:37 theme is so widespread that it

09:39 consistently ranks in the top three most

09:41 experienced nightmares, as well as being

09:43 the single most frequently reoccurring

09:45 one. But what's more is that it's often

09:48 accompanied by an inability to escape

09:50 where the dreamer falls and then gets

09:52 caught or where their legs get so heavy

09:53 that they can't move. It's not like the

09:55 dreamer wants that to happen. They're

09:57 actively trying to escape. And yet, in a

10:00 similar manner to the Reddit examples,

10:02 no matter how urgently they try, the

10:04 outcome is inevitable. I believe that

10:07 this is because the elements of your

10:08 dreams can mean multiple things at once.

10:11 But why this happens is particularly

10:13 interesting to me. We know it's because

10:15 in some way level four is where the

10:17 brain attempts to extract meaning from

10:19 the structured emotions it created

10:21 earlier. But extracting meaning

10:22 predominantly comes in two forms.

10:24 There's the top layer which is

10:26 subjective and personal determined by

10:28 things like your experience, memories

10:30 and how you interpret them. And then

10:32 there's the deeper layer which is

10:33 universal and instinctual shaped by

10:35 evolutionary pressures where the

10:37 inherited neural templates that follow.

10:40 Generally the structuring of dreams

10:42 comes from the top layer. So think

10:43 things like the people, length of or

10:45 situations in your dreams. While the

10:48 emotional gravity, the five themes from

10:50 earlier come from the deeper shared

10:52 layer. In your dream, both are present

10:54 at the same time. But to do that, your

10:57 brain uses something called an emergent

10:59 attractor network, which to keep it

11:01 brief are reoccurring motifs of memory

11:04 that emerge from the interactions of

11:05 neurons due to how they're connected.

11:08 This gives them two key properties.

11:10 stable concepts that can be recalled

11:11 consistently while also being flexible

11:14 enough to adapt to new experiences. The

11:16 adaptable part is where your control in

11:18 the dream, the top layer, comes from

11:20 while the stable part stays the same and

11:23 is where the elements you can't control

11:25 come from. So, for example, if you

11:27 experience a nightmare about being

11:28 chased, the person chasing you might

11:30 embody something from your personal life

11:32 that you've had a recent conflict with,

11:34 while the experience of being chased

11:36 embodies the universal fear of a

11:38 confrontation with inescapable

11:40 consequences. In the Reddit example,

11:42 with the unknown person appearing again

11:44 and again, this figure might reappear

11:46 whenever the dreamer is caught in a

11:47 reoccurring emotional cycle, but in the

11:49 stable layer, it's a symbol for a part

11:51 of them that they need to incorporate.

11:53 And is only when they do that the person

11:55 and the emotional cycle will stop

11:57 appearing. So in other words, the lack

12:00 of control is what provides the

12:01 consistent framework necessary to make

12:04 the dream interpretable while the

12:06 flexibility of it is shaped and colored

12:08 by your own experiences for whatever

12:10 you're going through. Still, level four

12:12 is where dream research basically falls

12:14 off a cliff. So I'm reasoning based on

12:16 the limited information I have. But what

12:19 makes this even crazier is that this

12:21 isn't even the deepest level. There are

12:23 some dreams where you know you're

12:25 dreaming and that awareness opens up a

12:27 whole new door into an entirely

12:29 different experience.

12:32 >> Level five.

12:33 >> It's rare and I've never experienced it

12:36 before. But in the people who get to

12:38 level five, something radically

12:40 different emerges. lucid dreaming, which

12:43 is when you're in a dream, but are aware

12:46 of the fact that you're in a dream. When

12:48 things are going your way, that's great.

12:50 You can randomly fly or jump through

12:52 walls or otherwise play around with the

12:54 contents of your unconscious. But when

12:57 it's not, it's terrifying. As just

12:59 because you're aware doesn't mean you

13:01 have control. And when this happens, two

13:04 experiences are reported more than any

13:06 others. encounters with hostile

13:08 characters and getting stuck in a

13:10 nesting dream. In the first one, there

13:12 are many reports on both Reddit and the

13:14 Dream Bank that explain what happens.

13:16 The person becomes lucid, gains

13:18 awareness, and tries to tell the figures

13:20 in their dreams that they aren't real.

13:22 In the good scenarios, nothing happens.

13:24 But in the bad ones, the characters get

13:26 angry. Sometimes screaming things like,

13:28 "You weren't supposed to know." And at

13:31 others, just turning around to lunge at

13:33 the dreamer. No one really knows why

13:35 things like this happen. The only thing

13:37 we do know about lucid dreams is that

13:38 parts of your prefrontal cortex

13:40 reactivate. But even that gets

13:42 complicated because in the second

13:44 experience, you don't have the same

13:46 level of freedom. As the reports go, a

13:48 person wakes up and starts their day.

13:50 They get dressed, use the bathroom, and

13:52 brush their teeth. At first, everything

13:55 feels normal until they catch the

13:57 reflection in the mirror. It's wrong.

13:58 Their nose is on their forehead, and the

14:00 mirror is a different color than it's

14:02 supposed to be. As soon as they realize,

14:04 bam, they wake up. Luckily, it was just

14:06 a dream. So, they feel a sense of relief

14:08 and then get started on their morning

14:10 routine again. But when they check the

14:12 mirror this time, their face is still

14:14 distorted. Only now, the mirror's color

14:16 matches reality. So, they panic and then

14:18 bam, wake up again. This time, they get

14:21 suspicious, so they go straight into the

14:23 bathroom and look at the reflection in

14:25 the mirror. Immediately, a sense of

14:27 relief washes over them. They're finally

14:29 actually awake. But then when they take

14:31 a second glance, their face distorts

14:33 again. Suddenly, bam, they wake up. This

14:36 time for real. In the reports of people

14:39 who have experienced this, this cycle

14:42 can happen again and again and again.

14:45 Sometimes seven times in total, all

14:47 while the dream gets closer to reality

14:49 every single time. It's a terrifying

14:52 experience to think about, honestly,

14:53 because as of right now, all we have are

14:56 reports. Some people think these

14:58 experiences emerge from the tension of

15:00 being aware in the system of the dream

15:02 itself. Others think it's because your

15:04 awareness can't sync with the sensory

15:06 input you get when you're awake. So the

15:08 looping is done to flip through dream

15:10 layers and waking signals until they

15:12 match and that's when you wake up.

15:14 Regardless, this is the final level of

15:16 dreams, at least based on our

15:17 understanding right now. And honestly, I

15:20 think it just opens more questions than

15:21 it answers. But maybe with time we'll be

15:24 able to figure them out. Anyway, thanks

15:26 for watching.
