More about mindfuck a stranger
Get 2 other friends and go into a mall. Target one stranger that seems like he or she will be there for a while. Then, over the course of the day, have you or one of your friends bump into the person and whisper ''you're in a coma'', ''this is not real'', ''wake up''. After you've said your line, just keep walking as if nothing happened.
