Last night I dreamed I was in a treehouse cobbled together with cloth and wooden planks.

An old grand piano filled the center of the space. I played Dr. John by Mika and sang while the wind and people swayed outside in the sunlight. It was in the key of A.

I woke up and hummed the song in my head and played it on the piano. I thought I had played it wrong in the dream. I was going to tell this story to my friend because in the dream it was her treehouse I was in, her piano that I played on. I looked up the song while I was talking to her just in case.

The song, it turns out, is in the key of A.
