Ah yes, I remember college. Wait until you graduate.

But depressing facts of life aside, you sound a lot like people who are against space exploration. Why bother? We have all we need on Earth. Or people who may have said to Christopher Columbus "why explore the New World? We have a nice continent right here." There are lots of rewards involved with the quest for lucid dreams, but for me the most compelling reason is simply the drive to explore. Why explore the subconscious? Because it's there!
