Anyone else having horrible dreams?

I had a dream on Monday night that I miscarried, it was very graphic and gut-wrenching. It took me a while to shake it, and actually get up and get ready. Then last night, I had a dream that I went to my 13 week ultrasound, and there was no heartbeat. This dream was also very vivid, and I was nearly hysterical when I woke up. I'm almost 11 weeks, and had a very positive ultrasound at 8 weeks. There is no indication that anything is wrong, but these dreams are killing me!

Anyone experiencing bad dreams?
