I have noticed that if I don't have a couple of beers before I go to sleep, that my dreams are much more vivid ande colourful. I am not sure why this. My alchold fueled sleep tends to give me dreams of work relate strees and unfinished projects. My clean sober sleep is almost an alien landscape of strange sites. I could try and claim that the booze kept these trance like dreams in some kind of check, but it is not manly to be scared of dreams.
As the surrealists say "freedom to the imagination", so I will get up and get another glass of orange juice.
