I woke up in the middle of sleep paralasys once with three greys trying to gank me, I popped out in my astral body and ki blasted one through the wall into another dimension, then the other two tried to paralize me again, and I grabbed one by its bony arm and felt it crunch as I pulled it towards me and headbutted it, and the third I pounced on and started punching in the face. This was about three years ago, haven't had a scary sleep paralasys episode since then. Demonic mother fuckers fucked right off.
