Love How OCD Subjects Change Suddenly

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?

I love horror movies and would watch them random sometimes even Terrifier cause art is my new favorite character. I just felt like I was a bad person for this⁉️ I don’t support his actions but I like his goofy faces he makes. I can’t enjoy anything no more Literally me rn in life

I have really bed harming intrusive thoughts and sometimes feels like it’s feeling! The thoughts happening every day and the hardest part is that I’m testing my self in head all the time if that’s what I am or want!!! Also, so many times feels like I’m been tricking myself and doctor or people and maybe I don’t have OCD, just that maybe it’s me really!!!! How can I know who I am really 🥹???!!??
