The Valley Of The Dead...

Ok so I remember in the movie "Waking Life" the end scene where the kid is talking to the guy from the boat that is playing the pinball machine and he is telling him about his dream. Well he says that in his dream he visited his dog and Lady Gregory and I'm pretty sure he says that that was not a dream and that in fact he was visiting the land of the dead. Now do you guys think this is true? That if we have a drema of being in the land of the dead we are not dreaming but we are actually visiting there?

What ever any body believes is speculative. I for one think controlled lucid dreams are a different reality. Possibly Lucid also. Non Lucid I think are created by the brain. My reasons for Suspecting this is in Castaneda's books.
