What's up with the nightmares??

Ugh. In the past two weeks, I have had terrible nightmares (when are nightmares ever good?) that involve two of my best girlfriends being violently raped - I was struggling to help them but couldn't get anyone to notice. I wake up crying - its so strange. I'm not reading or watching anything violent but maybe I'm mixing too many vitamins before bed. Good news is that my friends are well and dandy. :D
