Everyone has weird thoughts sometimes. Even people who don’t suffer from ocd. It’s the way we react to these thoughts that causes the problem. Try not to engage with them. The way I’ve started reacting is when I get an instructive though I just think ‘wow, that was weird’ then laugh and push it to the back of my mind. It’s hard and it doesn’t always work but it sometimes manages to get the thoughts unstuck. Hope you feel better soon, I know it’s tough :-(.
