I'm new to all of this, but was curious about any theories more experienced people might have as to the significance of lucid dreaming. To you, is it just entertaining and fun, or do you see it as at all spiritual or philosophically enlightening? If anyone has seen Waking Life, I'm especially interested in ways that lucid dreaming might tie into our conceptions of "reality." How have lucid dreams changed the way you think?

Thanks. Apologies if there's already been a thread somewhere on this.
