Fascinating. Some of my favorite writers have all used dreams as inspiration. Though I don't know if Lovecraft is a favorite of mine per se, I do like his work quite a bit, and so many of those stories were similar to this: transcribed dreams. I've tried to use the tactic as often as I can in my own writing.

Anyway, it's handy to keep a notebook and pen on the nightstand. & sometimes I'd say its better to lose a little sleep to be a dreamscribe than to go back to sleep and forget something you may have wished you would have written down.
