I started having intrusive thoughts/images about weird things three weeks ago and talked about it with my therapist who said it can happen in high anxiety periods and gave me some ways to deal with them and also recommended me a book about the same.

I was doing fine until I started having weird intrusive thought and images about a close friend of mine who passes away a year ago. I know it's intrusive thoughts but I feel so wrong that I have unwanted thoughts about someone who has passed away.

Am I weird? Or is this really just intrusive thoughts?
