Why are we awake? For me both worlds are the same. In a dream I can walk, run, talk, think, learn, and even more... In our dreams we also see objects as objects like in a waking state. But we don't give our dreams much value. You could learn to be a lucid dreamer and have control over your own dreams. For the shamans of the ancient Mexico dreaming was used to alter their awareness and to get closer to their spirit body or energy body. They were really the dreamers. more info, read my hub about dreaming.
