Dreams of molestation and rape by uncle?

Hi,

As a child and presently I would have (still have) nightmares about being molested or raped.

The molestation dreams are cartoonish and it's always the same man doing it. The rape dreams are more often violent and realistic. The molestation dreams aren't violent aside from being tied down.

Most of the molestation nightmares I would have as a very young child. What would cause this? My therapist thinks that the only explanation would be that I was molested, but I'm not convinced.

I have *some* memories that are suggestive and some people might classify what I remember as abusive but it was really minor and depends on who you ask. Nothing I remember is as explicit as what I used to dream.

Aside from molestation, what could cause this?

I want to know all of the possibilities and not focus on one like my therapist has been doing. She thinks based on what I recall (which is little and barely abusive if at all, I must say) and my dreams, it happened. What else causes this?
