Here's a interesting lucid dream experience I had some years ago. In what was just a regular dream I was flying high over a large church that had a red tile roof. Well as I was looking down on the roof and not watching where I was going I collided in flight with what was in the dream a flying vampire. I was knocked out of my flight and sprialing down towards a crash landing on the edge of the roof and just in time realized this is a dream and became lucid and regained control of flying and gained altitude and went on my way. Then I woke up. In the weeks after I re-entered the dream with the help of a Senoi dream coach and took up the dream at the point I became lucid and this time followed the vampire to his home and met with him. We chatted and became friends. This has become one of my fondest lucid dreams.
