Thought Experiment: Ask your subconscious mind for a dream where you meet real aliens. Ask out loud and sincerely talk to yourself about how fun this dream would be. Ask right before you go to bed and don't let anyone know or hear. Ask every night for a week and write down all the details you remember about all your dreams first thing in the morning. Also ask anyone sleeping next to you about their dreams. Your thoughts before bed effect their dreams too. I think their subconscious mind is effected by your emotions as you sleep. So you can give them the alien dream too. This experiment lets your subconscious mind explore the idea of "Aliens" in a more open minded environment. It's quite fascinating.
