Does anyone get a thought what if and then you start getting vivid images and stuff? It’s killing me

Two things are happening: I get thoughts that just keep looping. They almost feel like song stuck in my head. Also, I’ll imagine something and I feel my stomach drop. Then as the seconds go by I keep getting fragments of the this thought but with different details. For example, it’s kinda like how a “vision” is portrayed. I’ll get a glimpse of the thought and then it’ll rapidly expand into something worse every few seconds. I don’t know if I’m causing this or if it’s just an automatic thing like any other intrusive thought. It feels unavoidable, idk if this is a compulsion or if it’s just another manifestation of an intrusive thought. Apart from that remembering an intrusive thought triggers the full thought again and then it just keeps looping or expanding. I don’t know how to stop any of this. Help?

does anyone else get really vivid intrusive thoughts of the person who you are talking to (or close to physically) just randomly striking you violently? i keep getting them when i’m just talking to my dad one on one in the car & i get a flash of intrusive thoughts of him grabbing my hair & shoving my face in the dashboard. it gets me so anxious :’)

Does anyone else’s false memory intrusive thoughts of what could have happened feel very, very real?
