I'm a guy and I have a fantasy/day-dream where I'm in a position to save a girl from danger. Usually it's with a girl I know, and I imagine her in some sort of danger/peril, where she's about to be robbed/murdered/raped, etc. and I go appear and save her. What happens exactly might change, but it's always that same concept, of me saving a girl. I also occasionally have it as an actual dream, while sleeping.
