That's actually a pretty cool thought. I've always scoffed at philosophies along the lines of, "what if it's all a dream/simulation" because if it's perfect, and you only escape it through death, what's the point of holding that view? But if there's a chink in the armor, it becomes suddenly very interesting. Not that I think that's likely to pan out since it so badly violates Occam's Razor, but it's an interesting possibility.
