I wonder if misophonia is correlated with awareness. I'm maddeningly hyperaware of my surroundings, and have difficulty getting into "the zone" if there's too much auditory and visual stimuli. For example, if someone is talking in the same room, it's almost impossible for me not to follow what that person is saying; I can't tune it out unless there's something else that drowns it out. (Radios are incredibly annoying for the same reason. I can't sleep if I can hear people talking in another room; even music with vocals have the same effect.)
Being hyperaware has its benefits, of course, but it's mostly a curse.
