someone dies for some reason, (doesnt really matter) and they wake up in a blank room. they wander around for while seeing nothing but white until something catches their attention. turns out its a statue, or princess celestia, or whatever you want it to be that says, if you can cross this bridge without looking back then you can go to the after life. if not then you go back to the real world.

where it goes from there you decide. i only wrote this because right now if i had the choice i would run across that bridge as fast as i could, without looking back obviously.
