Based upon a story about "useless superpowers" I read, what would you do if you had the superpower to involuntarily at random see and share emotional state with someone elses life. You don't know where they are, who they are, or what their past life was. But you'll just "pass out" and experience their life from within their body for 20-30s and then wake back up as you.
So what would you make out of this "power"?
