Didn't know what a tactile hallucination was so I looked it up. So it's basically the feeling that something is there when there isn't anything? I have had that before, I have felt hands on my shoulders and felt like someone was rubbing my back. The first time I experienced the back rubbing sensation I was on the city bus and some guy was sitting behind me. I thought it was him but I couldn't catch him in the act! hahaha, you gotta be able to laugh at these episodes. I bet it is a tactile hallucination. Thanks for helping me figure this out...I've been searching for the answer for yrs now, but I ignored the mental side.
