When my friend sleeps, he doesnt ever dream. Any ideas?

The Stuff Dreams are Made of 
He does dream, everybody dreams. Tell him about some of the methods to increase DR, like mantra/autosuggestion and keeping a DJ.
Many people don’t remember their dreams often or at all, so they assume “I don’t dream”. However, we all dream, every night (as long as we get to sleep ). Tell him this. Maybe it’ll trigger something in his subconscious so he can have better recall.
