I can't decide what the weirdest thing I ever did was, so here are 2 of them. 1. I drove about 5 miles once before I woke up. I woke up on a very curvy part of the road. Negotiating the curves was probably what woke me up.
2. I almost shot my husband once. I was dreaming somebody broke into the house. He said it took about 5 minutes for him to convince me that it was him and not some hunter stomping down the halls in army boots. Needless to say I never knew where the guns were in the house ever again.
