If anyone is interested in using dreams as a part of spiritual practice I recommend reading 'The Tibetan Yogas of Dream and Sleep' by Tenzin Wangyal Rinpoche. Carrying awareness from wakefulness to sleep is one of those things in your life you'll never forget.
Kinda sad that only 18% of participants could respond. Who knows, maybe you could have whole groups of people entering one anothers dreams.. Would be great for interrogations, setting up archetypal areas like airport checkpoints to gain access to the identification part of someones subconscious. Might be less tinfoil than you think.
