I've been having weird dreams lately. I dreamed that all of my teeth were falling out, though I wasn't that upset about it in the dream. I just thought, well, I guess I'll have to deal with this after the baby is born. I've taken it as a sign to be really diligent about oral hygiene (brushing for a full 5 minutes and flossing 3 times a day).
I also had a very strange dream where one of my nipples (which in real life have gotten very dark and large) all of a sudden got very, very tiny and almost disappeared. In the dream, I was worried it was a sign that I had lost the baby.
