Not so happy dreams...

We found out two weeks ago we're having a girl :) on the 19th of the month we go for another check up and to see our little girl but lately I've been having crazy dreams.. Like this check up will show she's a boy (no big deal) but the one that really scares me.. She doesn't have a heartbeat. There's so many doctors in the room and I feel like I can't speak for breathe. I'm trying not to panic and cause stress but I can't exactly shake off the dream ether. Is this normal?? Anyone else?
