yes they can have nightmares. I don't know if they would about birth... that's an interesting thought...

But I know they can because Jaidan was never a screamer, used to wake up babbling and happy. Caught him watching a scary movie on accident, he was about 4 months old, he had nightmares for a couple of weeks every night! I know he probably didn't know what it was about but the music and screaming and sudden noises probably scared the bejeezus out of him. I never left the telly on while I left the room again!
