Why do humans stop seeing when sleeping?

[JuanMena]

Couldn't sleep today, and I began to think about, why we stop seeing when we're sleeping. I mean the following:

When I close my eyes in order to sleep, I often see a black picture with random flashing, unsaturated colored shapes going all over the place, like, dots, spots, lines, rings, cones, shapes... they're just floating around in the black background.

Then, I realized that while in this state, if there's light in the room, or light coming in from outside, I then see a "less dark" background. It's more noticeable when trying to sleep in the morning/noon, in which case, the same happens except the background turns a bit orange looking.

EDIT: When I'm like, physically exhausted, I see a kaleidoscope-like effect instead of just random flashing things.
This, except with unsaturated colors, somewhere between grey/brown.

Is there an actual explanation to why our brains decides to simply stop seeing anything?
Like, why or how it goes from random flashing shapes in background to a complete fully fledged dream?

I know, kinda weird question.

Biology 101

For us, and many other creatures of this earth, the body is resting as we sleep. Thus the body shuts down unnecessary/nonessential body functions in order to get the maximum relaxation it needs. [ie. rejuvenation]

In answer to the title question.

Pretty sure those are eye floaters, or some regular case of closed eye hallucinations, either way you get more of these the older you are

If I understood, I'm aware of my brain shutting down itself?

Couldn't sleep today, and I began to think about, why we stop seeing when we're sleeping. I mean the following:

Also, it's interesting how our eyes move when sleeping, they function with some kind of coordination with our brain, and whatever state/ visual dream we're experiencing.. Not sure if they move (physically) the same way they're doing in the dream (if we have a body in the dream) or atleast influences it (lucid dreaming).

When I close my eyes in order to sleep, I often see a black picture with random flashing, unsaturated colored shapes going all over the place, like, dots, spots, lines, rings, cones, shapes... they're just floating around in the black background.

I see none of that. I personally see colors floating with no particular physical shape, just flying around like waves up and down, right/left etc. the first color i see is always magenta/ or one of its shades (i noticed this like since i was 6yo, srsly, i thought everybody had them), as the moment i start focusing on it it starts changing color.. It's like Chakra colors.. Sometimes i see white (although rarely), just encompassing my whole body..
Also, since we're in the topic, when i have a bad dream or a nightmare, meaning i just experienced something that was manipulated and orchestrated by some "entity" (regardless if you believe in this sorta stuff or net), the moment i wake up from the bad dream i see a red energy wave thing that was close, if not in my body (stands out against the pitch black darkness), moving away so fast then disappear/dissipates. Make of it what you will, bit this has happened to me many times, can't be just coincidence (and sorry for the tangent?)..

EDIT: When I'm like, physically exhausted, I see a kaleidoscope-like effect instead of just random flashing things.
This, except with unsaturated colors, somewhere between grey/brown.

I see this when im trying to fall asleep, in colors, although not regularly. In a similar vain, i'd see random pictures, locations or situations involving people, nature or animals, this stuff i probably have never seen before, but i think it's my brain showing me its AI art program, usually doesn't last more than 2-3mins..
This is the creative part in our brain that make dreams (in all its forms), the one translates "thoughts to visuals" like AI does with "text to art"..

The brain turns off many body functions including that, body parts (organs, cells etc) to rest and recover during sleep. Even the brain areas of it get to take a rest (apart from REM sleep), leaving only essential stuff like breathing, heartbeat & digestion/bowed movements etc (stuff that you do unconsciously), stuff that you'd def die without.

Ya still wetting the bed at that age??

Anyone else has "Exploding Head Syndrome"?

I was 25 years old when I learned that the fireworks that woke me up in the middle of the night, weren't real.

 

[AncientBoi]

Ya still wetting the bed at that age??

yup. The last one I had was on your bed . Sorry bout that

I've only seen this in two cases:

- Chinese jay walker tripped / fell under a massive 16 wheeler.
- People with shotgun in mouth pulls the trigger.

Mamma, oo-oo-oooooh!

Okay, it's literally what it sounds like ಡ⁠ ͜⁠ ⁠ʖ⁠ ⁠ಡ
Haha.

No, seriously.

You'd be sleeping and suddenly you hear a loud bang/explosion, waking you up. And that happens regularly to me and always thought it was fucking children doing fireworks outside (it sounds like fireworks) when in reality it's a sleep syndrome.
