The game is centered around a ww2 stealth assassin who is in a coma, and you're playing her memories of her missions. When you use morphine in a mission, it blurs the lines between the dream and reality. It's not flowers flying around, it's blood cells, and she doesn't get into her underwear, it's the nightgown she's wearing in real life. It's still pretty goofy, but it actually makes more sense than those other impressions make it sound.
