I had a dream

So a couple of days ago I was reading through some posts on this app and came across someone talking about incest ocd. I was triggered almost immediately and have been having these thoughts about my brother and having imagery in my head about him (I saw his nudes when I was being nosey on his phone one time) and now can’t seem to get it out of my head. I just want these thoughts to end I feel so weird I can’t even be around him. Also, my anxiety isn’t even that high which makes it feel more real. I haven’t been anxious with a lot of ocd thoughts lately and apparently this is a sign I’m getting better because I can carry on with my day as usual. But it does feel more real and like I like the thoughts. Please help.

I know this is terrible. And I shouldn’t be having thoughts like this but I read someone else who had these thoughts and my brain remembered a time I had an intrusive thought about my brother and it made me think what if I’m attracted to my brother. Now when I’m around him I get worried I’m going to have some sort of physical feeling or attraction to the point I basically freak myself out and have intrusive thoughts that I do or am while talking to him. And now I’m just avoiding even being home. Ik it’s awful and I never felt anything like this before and I know I don’t have any but I keep thinking about the feeling aspect. And whether those feelings/thoughts were true.

i've had a terrible dream this morning about my fears getting pretty much confirmed. I've avoided to address this the whole day doing a rehearsal, going at the bar with friends and playing games till 2 AM. I don't know how to move on from that dream. Something horrible happened. I felt genuine arousal and now everything seems meaningless. That dream basically confirmed my fears and invalidated all the things I reassured myself about false attraction and staring ocd. I don't know how to proceed after that dream. My hopes of being a good person got crushed. All is meaningless now. I don't even feel that much distress about it. Probably because I shut it down and didn't fully address the dream, reality hasn't kicked in yet I feel defeated. I feel like a **** and my identity is in shambles. Even at school I felt defeated and was wondering what's the point. "What's the point now of even avoiding sophomore and junior girls""who cares feel attraction like your friends do" and I felt like I stopped caring about my moral code and when I realised that I didn't like it. It all feels meaningless. The one thing I didn't want to feel I felt and now l'm empty. I don't even feel distress no more.
