I do get these sensations/hallucinations from time to time, I'll feel someone playing with my hair, I've felt something trying to rip myself out of my body (I know doesn't make sense, buy that is what I felt), I've felt bugs crawling all over and biting me. I've felt something/someone cutting into my wrist or behind my knees, and idk what else, that's all I can remember off the top of my head. Idk if they really are hallucinations, I can't really tell you, but yes I've had similar sensations before.
