Dream: Burning leaves

I dreamed that I was woken up by the scent of burning leaves, and I stepped out of the house to find out who had started a small bonfire. I wasn't dressed to go out, so instead I peered over the wall. I saw a friend who passed away this year. He smiled at me and I was startled to see him, remembering he had died.

Then his face became that of his brother's. 

"Oh, hi," I said, "I didn't know you were here." And I thought you were your dead sibling. "Has anyone been burning leaves?" I asked.

He shook his head, and I went back inside the house to sleep.
