Last night I had great difficulty getting to sleep as I had consumed way too much caffeine to assist a long drive back to town. When I did dream, I dreamed of another magician's familiar. That being more of a private conversation with someone/something that didn't consent, not that I was lucid enough to ask, to publication, I am keeping that one to myself.
I will say that I found the conversation interesting. It did involve recognizing something as a spirit, as opposed to a being with corporal form. The encounter has no setting. It was held in more or less blackness.
