Run around, Punching entities and ripping wallpaper and die because i tried to fight an entity.
Or if i was stable enough, I'd go around doing shit normal people would do, Find shit in the level 1 co. supply crates, Go to level 2 and shit myself seeing an entity, Go to level 4 if i'm lucky, Take a drink and not bring any bottles because i don't trust the water in the backrooms and die of dehydration.
