Welcome to Dreamviews! Congrats on becoming lucid! Dreams can get very weird/crazy. When I am lucid, I too wonder why my mind did this or that, lol. Its a very enjoyable experience just exploring and seeing what your mind randomly produces. Good Luck with your future efforts!

Oh, I suggest you start a Dream Journal if you haven't already. I would be interested in reading more of your dreams (I am sure others feel the same way). good Luck!
