Now, I'm not totally sure hallucination is the right word for what I'm going to describe, but I think it fits the best. So forgive my ignorance if this doesn't fall under the category.

When I was still in my last relationship, I was incredibly afraid of being cheated on. To my knowledge, from what I've heard from his friends, the man I was with has never been unfaithful. But he is a pretty flirty person who's DTF any cute girl, so this is probably what triggered me so much while I was with him.

Most days, I was okay. I trusted him. But the days I couldn't? Holy shit, I was so paranoid. My fear was so intense that on a few occasions, while he was conveniently away from me, like out of town or just hanging out with other people, my brain spiraled way out of control.

In my minds eye, thoughts, feelings, &amp; images forced their way into my awareness. It felt like I was picking up on him thinking about &amp; desiring to cheat on me. The intensity increased &amp; I felt like I was feeling him commit the act. So I'd be sitting there, having an anxiety attack while being plagued by a nightmare of him boning some random girl &amp; relishing the feeling of cheating on me.

I don't know why I'd even mildly hallucinate such a thing when I never had proof he was cheating. Maybe a closeted kink? My God awful insecurities &amp; low self esteem? 

Whatever the case, I had a handful of moments where my brain was totally convinced he was cheating on me right then &amp; there &amp; I was forced to bear witness to it telepathically. Anyone else ever experience something like this?
