Arthur shook his head. "It's difficult not to lose yourself, when you work from real memories." He pointed around at a few things, including the out-of-place vault door, and some light fixtures which didn't match. Minor details, mostly, but still enough to throw off the look of the place. "It gets really easy to lose track of what's real and what's a dream. We'll need to get you a totem before we go messing around in your memories. A small item, something that you can carry around in your pocket. Something that only you know the feel and weight of, so no one else can replicate it in a dream."
