Why Do I Have Dreams Of Fictional Girls?

I have had about 3 girls from fictional movies/tv shows that I have had dreams about. Nothing sexual ever happens in them but I have a dream and when I wake up, I am attracted to them. Does anyone know why this happens? Like I said, nothing sexual happens in them.

How old are you? You are watching too much TV/movies and your hormones are going crazy.
