My belly-button went "pop"

When I got up in the morning I remembered a lot. Then I left the house and went to work and now I can remember very little. I do remember though that I saw that due to some strange condition my tummy was as big as if I was pregnant. Suddenly my belly button went "pop"and started protruding from my belly. I pointed this to my mother and she said I must be pregnant after all. We were crossing the street opposite the kindergarten I went to as a toddler. I was disgusted by the way my tummy looked and expected it to go back to normal but it didn't. I slept some more and had another dream, but as I have already mention, I have no memory of it anymore.
