You said you believe in astral projection. Were you OoB prior to this happening? I've come across accounts where people have projected and not fully returned, they feel sort of "half in". Typically they project again and work on a full return. I've always seemed to make it all the way back myself, but there have been a couple times where it took longer than normal, and I had to sort of fidget my way back in. Makes me nervous and paranoid for a while after. Maybe part of you is in a place where this stuff wouldn't be frightening. I have trouble sometimes with being halfway, part of me will still be in a place where what I witness is downright scary, and I end up retreating and being jumpy for the rest of the evening.
