I've heard people say that if you die in your dream, then you die in reality. However, i died in my dream once. It's a complicated scenario but I'll try my best to explain. So in my dream, I was on a water slide, I turn around and I see a huge tsunami and all of a sudden there's a thunderstorm. I get caught up in the water and I basically drown to death (i could feel it in reality.) Then I black out, and I ask myself if i was dead and where I was. Then later, I wake up and I'm lying down in an empty room. Pretty scary stuff.
