I am a little disturbed by your statement: "This is why seances are conducted, to unite the energy of the group for the entities to feed upon." As it is impossible to positively identify with whomever you are communicating with, unlike you, I'd not place myself into situation where some entity could likely suck the life out of me, at the very least. It might like the way I "taste" and follow me home, where I do not wish to live with it. I have a great interest in the supernatural and paranormal. However, I study it from a safe distance..., and I'm sure it is studying me as well.
