I like that Zen Koan about going off to dreamland to meet the sages. I practice meditation and I used to fall asleep while meditating, much to the amusement of my wife. But, while asleep in the dream state I would have some very insightful dreams which were more profound than what I would get through normal meditation. I've since begun to pay attention to my dreams and reflect upon them after awakening. Much inner wisdom there.
