I had a dream about a week ago in which I had a false awakening in my parents living room. It was night and I could see a clear silouhette of a Christmas tree against the dark blue sky through the open curtains and thought to myself:

"Why would there be a Christmas tree up in December? This must be a dream!"

And thus became lucid. I thought it was rather funny afterwards.

Anyone else become lucid through strange or false logic?
