This is the second time now that I dream I’m pulling out my ex boyfriend’s teeth (he’s a dentist) I don’t know what can that possibly mean or why I dreamt it again. This second time I also dreamt he raped me which was very vivid and uncomfortable, and later I became a witch... I have no idea what any of this means but it’s a dream I can’t get out of my head for the whole day. 

Sometimes such a dream can be just an indicator of a complex nervous state - fatigue or anxiety. I try to say such dreams out loud. Usually it’s enough just to tell a dream to someone to throw it out of your head.
