I'm sorry you had such an unsettling nightmare. That must have been really hard to wake to.
I tend to agree that dreams can manifestations of fears or thought processes we can't seem to put together while awake.
One thing to keep in mind is that it was just a dream. It wasn't reality. T didn't actually do any of the things you dreamt about.
Give her a call or send her an email and let her know the dream disturbed you (as suggested above).
