ok i was just about to take a nap, right? well i layed on my stomach and was about to fall asleep ( still awake at this time ) then i felt pressure on both my shoulders pushing down and made my back go into a V arch shape by itself.... really weird.. and only happened once. but i have had i in the past where i was falling asleep and i thought i was falling off a cliff ( still awake but not fully ) and tried to grab something to keep me from falling ( but i wasnt falling ) kinda like your falling asleep and then you get this falling sensation and freak out... so yeah.. anyone else had these two things happen to them?
