I see psychedelic geometry when i close my eyes and are 100% sober
So i made this a little hobby of mine, right before sleeping, and when i put my head on my pillow, i just close my eyes and doze off, but before sleeping i just let my brain generate images for me to watch before i sleep, the images look so real like watching a 4k tv, could be anything a car a nice sunset, food etc, and sometimes i choose to control what i see, and other times i manifest these shapes at will and 100% sober. I know they're related to psychedelic trips, and i personally believe that they have something to do with the universe.
So my question is, is it normal to see these shapes when closing your eyes and being sober?
