You're certain this is real. Zhuangzi wasn't, and he had a point.
Sophia Butterfly Dream Reflection
Zhuangzi, the great Taoist philosopher, once dreamed he was a butterfly — flitting about with no awareness of being a man. On waking, he couldn't say whether he was a man who had dreamed of being a butterfly, or a butterfly now dreaming he was a man. The parable isn't a trick question; it's an invitation to notice how much of your certainty about who you are is just the dream you happen to be having right now. Writing down what feels solid, and what doesn't, is a private way to test it.
