Abnormal and controversial dreams

Old dream:
This is an old dream, but very memorable due to how strange it was. I had this dream before I started writing my dreams down so I'll have to go off memory. I remember being in a pink house that I've never seen before, and going into bed with my Mother. Eventually we were committing incest when suddenly she turned into a buff/muscular man. As she turned into a man the house started to float into the air, far up into the clouds. The walls started to fall off the house and people started jumping out, down to earth. Then I woke up.
