"All your time is spent in dreaming. Your sleeping and your waking dreams have different forms, and that is all. Their content is the same."
I had an amazing experience the other night. I'm not sure if it will seem extraordinary to anybody else, but to me it really was.
I was dreaming in the night, and it was just about walking around in my old home town with some friends and having various experiences. But it was parts of the town I had not seen before, and since I know every inch of it, I knew it was not real.
Whether for that reason for inspiration, I became aware that I was dreaming. And I became aware that I might wake up, but not necessarily immediately, and it did not matter.
The really amazing thing, though, was that the dream and everything in it was astoundingly detailed. It was every bit as detailed as what I see in "reality" every day. Perhaps even more, I think my eyesight was better in the dream.
It was a fantastic experience to walk around in this world which I knew was a dream, and yet it continued, and yet it was fully as detailed and real-looking as anything I'd ever seen.
It might not be proof that "reality" is actually a dream. I don't know if that can be "proved". But it can't be proved that it's real either. Any proof you need to prove that it's real, you can also dream up!
But it did prove to my personal satisfaction that a dream can seem at least as real and detailed as what we call reality, and therefore there's no reason, apart from emotional necessity, to assume that reality is not a dream.
