Last night i was meditating in my bed laying flat arms above my head flat when i sleep (yeah i do this lol) so im laying there trying to focus on not focusing meaning try to clear my mind. Time passes and i believe i start to not feel my limbs and almost go into a trans-like state. i feel my stomach clench up but its not stressing me out at all like say a crunch would when you are work out then i feel my arms above my head start lifting as this is happening im still trying to concentrate, i feel every muscle in my body well above my waist clench up and tighten but im still breathing normal as if nothing is happening at all which is weird. every muscle seems to fire up and clench up individually as if im working out but again i don't feel stressed. and this is a slow process, before i know it im almost sitting up straight arms almost fully extended in air my body about at a 75% incline from the bed. i open my eyes and all of a sudden drop back into my bed and start breathing as if i had been doing a marathon. i don't know if i was about to AP or if i was beginning to levitate. I guess my question is has anyone else felt this???
