frightening dreams

I've had many nutty dreams in the past couple of weeks, but last night seemed to be the night of unending nightmares. The first one woke me up and kept me up. It involved my next ultrasound. In my dream the ultrasound tech told the that the baby is measuring behind and the heartrate is way to low to be normal. The heartrate in my dreams was in the 60's, and the ultrasound tech told me that this baby was destined to die. When I woke up, I got up out of bed and got myself a glass of water. That dream seemed way too real. I played it over and over in my head. I couldn't fall back asleep, and I couldn't shake the feeling that something was wrong. I think I'm going to be plagued with these feelings until I give birth to a healthy child. My second dream was something involving being trapped on an airplane. I have an unnatural fear of flying and will be flying next month. In this dream I was put on a 28 hour international flight, against my will. I was told I'd stay on this flight for 28 hours, and then told I wouldn't be able to get off the plane and would have to fly back another 28 hours. I HATE bad dreams. I know that they are based on anxieties that I have, and that I should just try to put them out of my mind. It's alot easier said than done though. I'm hoping tonight I'll get a good night's sleep and have dreams filled with butterflies and rainbows.
