It makes sense, then, that you would be dreaming about sex, since it's a big concern during your waking hours, too. I suspect you dream about being raped because you don't think it's right/appropriate/acceptable (?) for you to give a man permission to have sex with you. And you are attracted to older men, so it's not surprising that the men were older. Freud said our desires come out in our dreams.

Perhaps the Catholic priest represents such mixed feelings. They do, alas, have a known history of sexual abuse, too. And Mormons are opposed to sex outside of marriage, too, aren't they?

You want sex; you are appropriately curious about it; Maybe it's sort of magical, scary? But your upbringing and now your personal beliefs tell you sex is not appropriate for you. So, you were running away from the priest and the other men.

Pardon me for asking, but is sex for one (masturbation) considered wrong by you, too? I think you do need some way to take care of your healthy, normal needs.

Of course, therapy can help us. If you keep having such dreams and they upset you, then I would suggest therapy for you.
