Tired

Went to bed last night around 10pm.  Woke up just before midnight from a horrible, horrible nightmare.  I normally don't get scared or feel fear ... but last night was different.  I got a full blast of terror, it was intense.  I knew it was just a dream so once I was able to fully wake up and shake it off I was okay but I still didn't sleep well the rest of the night.  I woke up at 3am, 4am, 5am, 5:30am and 6am ... finally I gave up and just got up.  Needless to say, I'm tired.  I hope I can sleep tonight but I get the feeling that it will be more of the same.  I haven't slept well in several weeks.  I'm over trying to figure it out ... I could care less .... I just want to find some peace in my dreams and sleep.  To sleep and actually awaken rested ... I know it can be done (because I've done it) but it's not something I've been able to accomplish lately.  What do I have to do to sleep?  I'd give almost anything to rest.
