I fantasize about men in authority, and i'm a senior in high school.

I'm eighteen and in my last year of high school, but I have highly detailed dreams of a couple of men that are figures of authority in the building. I understand that if I see them every day, it would be easy to explain their presence in my dreams, but it's very rare for me to see the two men, at least now. One is a new Assistant-Principal, and one was my sophomore English teacher. I've had over a dozen dreams featuring the latter over the years, but the first one with the AP was last night. They almost always have a sexual overtone, but not in obvious ways. In most cases, they exert some very mild sort of power or authority over me, or are manipulative. I don't know why, but my reaction is nearly the equivalent to a wet dream. I don't get it, but this influences me to be attracted to them in real life. Is this normal?

(Of course I don't act on it, and nor would they, clearly.)
