Keep a sketch book and some promarkers beside your bed. In the morning when you wake up try and draw what was in your dream.
for these drawings I did no pencil line work, just tryed to draw what I had seen straight with pen ( favorite way of drawing) sometimes i would forget what i was drawing as i bacame more awake and the dream would leak from my head, but these are beamed straight from my sub concious.
These next few- I was stuck in the modern part of the museum at night and robot men with torches for eyes were watching. (re-occurring)
Not dreams- the two places i kept waking up.
