I had a rather strange projection the other night, in it I was in this place that had a shiny floor and blackness everywhere (in itsself odd to me), when suddenly I was grabbed from behind, it was rather uncomfortable as it wouldn't let me move, I could grab onto its arms and struggle but my hand would phase through its when I tried to pull them away. so I brought myself back to my bed but didn't leave the meditative state (I can normally do this this 2 or 3 times before I loose it), but when I tried to project again there was something standing on my chest, not on my physical, it was only when I tried to move.
