Since most of the interests listed on your title page relate to music, why not write about a musician?
Now, since you haven't answered a question for ten months, why not start with a guy who was injured and, for ten months, was unable to remember who he was. Then he sees a musical instrument (you decide what sort) and begins to play. Slowly his memory returns, but it's a bit fuzzy still. He begins to dream about who he was -- but were those dreams memories, or fantasies? Was his life good or bad? Was he a nice guy in his forgotten life, or a crim?
