I dreamed about someone other than my SO

I did, but it was a pretty PG thing. I don't know if it's the right thing to tell him about having it. I had it before I told him that I didn't dream about anyone, I brought it up because I didn't know if it was normal/ bad to have done that. I know it's involuntary but I don't know if it's something to tell him about to worry about. We are in a long distance relationship and we are very serious about each other. I just don't know if it's worth bringing up or if it's not that important. I don't want him to feel out of control of the situation because he's not. I would really appreciate some advice!
