The experiment involved participants utilizing specialized equipment including sensors and earbuds. On September 24, one participant sleeping at home induced lucid dreaming, a state in which you are aware that you are dreaming. It is apparently a trainable skill, although I have only ever personally experienced it a handful of times throughout my life.
Ideal: "Oh wow! I could hang out with friends in my dreams! Conversations on the moon!!"
Reality: "You’re late"
Bonus: "We don't have to pay them anything because they're not physically at work!"
