For the last 6 years I've been experimenting with lucid dreaming. It happens very rarely, about 2 or 3 times a year. For anyone that doesn't know its a dream where the dreamer knows its a dream and can control it.
Last time it happened was a week ago. I was in Norway and had to meet friends of mine the next morning. I dreamt I was hungover and thought "Oh ****, I have to meet these people tomorrow...oh ****, thats in Norway! what am I doing in Ireland....oh wait, this is prob a dream"
Still in the dream I tried to fly, which I could, which indicated to me that it was a dream. Does anyone else lucid dream? Its a balance between doing what you want and waking up. The film Waking Life indicates the two indicators of dreaming is not being able to change the light levels and not being able to read digital dials, which is both true.
