Can you say any more of life?

A dream is real while it lasts. Can you say any more of life?

These are the words that have been ringing in my head for the past hour. I just got done watching "Dreams: Cinema of the Subconscious" on my inception Blu-Ray disc... Whoa.. That last bit REALLY sparked the philosophy major in my being.. Really.. It's so true but it's really mind boggling... I just couldn't find an answer to this statement. Thoughts?...
