I tried that, "pay attention to written things" idea in a dream last night, and saw 2 words written (it's bothering me that I can't remember them), and I thought, in-dream, "Oh I have to check back!" but woke up from that thought. Will try more.
Im really not interested in any of this corny, "Im gonna fly!" shit though. I think I'd be more interested in seeing people that I love die or seeing things I care about crumble. Maybe also play with like altering my physical body to ludicrous proportions and then seeing if it affects tissue.
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
