I went to sleep at 10:45 and set my alarm for 4:30, i got up for about 10 mins and then i went back to bed to lay down. While i was lying still for about 10 - 15 mins trying to lucid dream, i got this feeling like my body was tilting backwards and kind of flipping. I also saw visual things like colors and flashes. I ended up falling asleep because i gave up and turned on my side and went to sleep. Does anyone know what that tilting/flipping feeling was? Also, does anyone think i was close to a lucid dream?
