Invisible man in the grey suit

I startled awake last night because in my dream there was a man who was speaking to me. He had on a grey suit and a fedora... but he was invisible.

I lit a candle then went back to sleep (tea light candle in a glass jar - no possibility of fires). The rest of the night I had other weird dreams... one of them had dragons in them - friendly dragons.

Can't imagine what my dreams might be like if I actually did drugs or some such thing...
