is it normal in ocd where things randomly just remind you of what your intrusive thoughts are about? like lets say you get a IT about rainbows and see something and that thing reminds you of rainbows even though theres nothing obvious about it that are related to rainbows

OK, this might sound really dumb, but when you guys get intrusive thoughts, do they just come once and then go away? I’ve heard that repeatedly thinking about an intrusive thought is considered ‘checking,’ but it doesn’t feel like I have any control over how many times it comes up in my head. It’s not like I’m trying to check anything—it just keeps showing up, almost like it’s terrorizing me every time. I can’t seem to stop it from looping, stop remembering it, or prevent it from coming up. Every time it does, I feel horrified, and I already know it’s going to horrify me. I don’t think I’m actively trying to see if my feelings have changed, so is this still considered checking? How do other people get an intrusive thought and just move on? Doesn’t it pop up a million times for them too? I always thought that was normal, but now I’m hearing this could be a compulsion, and I feel really confused, scared, and lost. Is this why my OCD feels so extreme? Because I really don’t feel like I can control how many times the thought pops up.

Does anyone else get fixated on one “topic” with their ocd?? like for me trains and guns are mine. like i’m scared of trains and im scared to be around guns because that’s what triggers my ocd and makes me convince me that that is the way to go. i literally worry myself into thinking im going to sh*t myself when i don’t even have a gun but my ocd convinces me. idk if im explaining it good, but its a real struggle. just need some tips & advice

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
