I had one of these last night in fact, it has been popping back in to my head this morning. I wouldn't say it was really disturbing, more annoying to me. My conclusion is my thoughts about it were - ridiculous, so maybe that's the good part, I'll let it go.
I know why I have them, I know that it's my mind trying to work through it. I don't hold much stock in it since I already know why, but yes, it's rather annoying!
