Some of the best art, music, and literature all came about while the author was semi-conscious, inebriate, high, doped up, or otherwise encumbered. That is not to say I condone making oneself delirious with illicit substances, but what it does mean is that I do not fear it, and recognize that it even happens with those who consider themselves "sober." Just think about it. If you're really tired, you're body starts to act as if it were drunk. Your speech becomes slurred; everything is funny; you're more relaxed; your social inhibitions start to fade. And, it's not a bad thing.
How many times have you woken up in the middle of the night with a fabulous idea, only to discover the next day that it was nonsensical or only half-conceived?
But, on the other hand, sometimes those ideas are brilliant. There is a small path and gateway in between the conscious and subconscious mind. One side makes the other relevant, and both can act in a limited but ingenious concert.
I write my best poems at night after just going to sleep. I solve logistical life problems often after being konked out a little while. So, in my less than sober insomniac state, I solve the seemingly insolvable problems of the conscious "real world."
And, sometimes its just fun to ride a magic rocket ship with your dragon friends.
