Cloaking
I don't know if I've had this power before, but I spent a lot of my dream last night cloaking. If I focused really hard, in a way that makes my whole body tense up, then people wouldn't be able to see me. That, or they could see me, but their brains wouldn't register it. People spent time trying to find out what it was that was moving or taking things from the store. It was me. Hah! Sometimes I'd take a step, someone would hear it, and they'd lunge at me. I'd be dodging and darting all the way around the store. I'd cling to the ceiling, and people would try to jump up and swat at me even though they couldn't see. Eventually I fled the store and flew away back home.
