dreams
. He could become anything he wanted. A tree. A wave. A hawk.
Whenever he became a thing, he couldn't remember what it was like once he was awake again. This was because he was human in the daytime. Living through his human perceptions and cognition. When he became a tree, the mode through which he interacted with the world could not be translated to sights, sounds, touch.
