Oh yes babyboom, but in those kind of conditions, and I mean seriously stressful, raised cortisol levels can lead to aggression from the child later in life. Leaving a child for extended periods of crying can have the same effect I believe.
But dreams are a natural way for the mind to deal with stress or new experiences etc. Baby will be fine! I don't want to scare OP!
Crankytwanky -- that is a very interesting theory. However, I felt that mentioning the raised cortisol levels may have been more of a stress for wafflesmum than a comfort -- one more thing for a worried mother-to-be to worry about. Which is why I mentioned that women in war zones do deliver healthy babies and that nightmares in comparison are completely benign natural occurances that will have no impact on a developing fetus.
