Do you ever just get a thought in your head and you’re like “wow if i thought this then it must be true/it must’ve happened etc” “i thought about it for a reason”

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

Ii spoke w my bf this weekend and he mentioned that he has thoughts just like me, but his don't bother him like me. I then felt a lot better and he tried dissecting one of his thoughts like I usually do and realized it felt more real for him after. That made me realize that none of my thoughts were ever true and I blew them up. However, yesterday I had a thought ab “wait wut if you liked that one guy? How dare you bc youre supposed to love your bf and not secretly like someone else” and treated it as I usually did bc I accidentally wanted to see if it was true but didn't rlly but I would check to see if it was there and now that thought feels so so so real now and I feel really bad how do Ik it's not real? I feel so bad and guilty bc lividly this makes 0 sense but it feels so prominent. It felt pretty real when it happened yesterday too. And now I feel awful bc how is it possible after my clarity the other day? Why does it feel so prominent 😞😞😞

When I say I feel like I like a thought, I don’t mean the OCD is telling me like a thought or that I concluded that from a physical sensation. I mean, I genuinely feel like something in my brain lights up and it feels like I like it mentally. Whenever I hear people talk about liking thoughts (excitement, arousal), I always see things about groinals or heart flutters. Physical things. I don’t think I really ever see people talk about the mental sensation if this is even a thing. I just wanna know if anyone relates to this or has found an explanation for this because seeing it from an analytical point of view seems to help me sometimes. This is so, *so* especially hard for pocd themed thoughts :( Anyone relate?
