Had some interesting "wake-up-cognitions". After waking up, but still with my eyes closed and half asleep, I saw the following (added some eye-bleeding-inducing paint scribbles too

):
First I saw video-tape-like bands hanging in otherwise empty space:

Then I saw a grid made out of similar squares. There were weird ornament-like patterns with lots of variety in the squares. Then the image vibrated, and after it stopped vibrating, the insides of the squares were "animated" (moving). After a few seconds of looking at it, I realized the patterns in the squares might actually be fractals -- they looked so simple and structured, unlike the "clichee-fractals" we know, that's why I didn't immediately think of it. (I filled out two of the squares in the image, just imagine the rest look similar

)

After that, I saw an image of a room that was kind of warped, distorted, with the walls being partially cuboids. Basically these cuboids were part of the walls but also somehow in the room. If I had to guess, this was an attempt to visualize mulitple dimensions, which we can not comprehend with out 3d-minds. The walls of the room, including the cuboids were covered by the grid that I had seen before, like a texture that got applied to the room. Was kind of interesting to see how this cognition "evolved" in stages.

I actually had a similar cognition over half a year ago (I think, I got no sense for time lol), only that there it wasn't arranged in squares but rather a fractal mess all over the place. It also ended up covering a very similar "room" as a texture. So maybe I saw the same thing as back then, only that today a lot/ most of it has been restructured by us so that we can actually work with it?
