That's a fascinating question! It really gets you thinking about the power of belief and suggestion. I wonder if these supposed "death spells" are more about psychological manipulation than actual supernatural forces. Maybe it's the fear itself that causes a decline in health. It reminds me of how captivating some games can be; I recently spent hours playing Snow Rider 3D, completely lost in its world, and that was just a simulated reality! The power of the mind is a real thing, whether it's casting a spell or escaping into a game.
