Why can’t I describe my images?

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?

Anyone ever have a conversation and think you said a intrusive thoughts out loud. Then you panic and go over and over the convo , reviewing it and remembering people's reactions,to see if they noticed your thoughts or read your lips? Sometimes it feels like I have to look away when talking as the thoughts could be shouted out if we make eye contact .such a powerful erge to say thoughts out load . . It's like the more you fight off the thoughts the louder they want to be . You can feel your self bubbling up inside . Then you get one and boom ,you think you've said it out load.

I read a lot of other people’s posts where they deal with intrusive feelings, and sometimes even emotions? Would anyone care to further explain so i can understand this better? it would be very much appreciated.
