I have had this sensation since 2 years. That something happens around my head/mouth. Its an annoying feeling but I dont panic. I associate as an sexual act even though at first I didnt experience it like that - just like an invisible image infront of my face I wanted to get rid of. Its annoying in the same way as like a fly flying around you. Lately this experience has changed shape and I do really experience that I have something in my mouth and I want to take that thing/thought away. It happens many times during the day and especially when Im not busy with other thoughts. Someone know what this is? It doesnt feel like a flashback since I dont feel much. Its not like a memory or thought. Its to close physically but still its invisible. Am I making this up?
