AM I awake or am I dreaming?" I ask myself for probably the hundredth time. I am fully awake, just like all the other times I asked, and to be honest I am beginning to feel a bit silly. All week I have been performing this "reality check" in the hope that it will become so ingrained in my mind that I will start asking it in my dreams too.
If I succeed, I will have a lucid dream - a thrilling state of consciousness somewhere between waking and sleeping in which, unlike conventional dreams, you are aware that you are dreaming and able to control your actions. Once you have figured this out, the dream world is theoretically your oyster, and you can act out your fantasies to your heart's content.
Journalistic interest notwithstanding, I am pursuing lucid dreaming for entertainment. To some neuroscientists, however, the phenomenon is of profound interest, and they are using lucid dreamers to explore some of the weirder aspects of the brain's behaviour during the dream state (see "Dream mysteries"). Their results are even shedding light on the way our brains produce our rich and complex conscious experience.
