Are there differences in types of walk-ins?
I know some believe a walk-in is permanent and some believe it can be temporary but does it always seem like a clean slate type?

What if a walk-in observed the host from afar prior to waling-in and/or perhaps shown some of their experiences almost like a movie? Maybe it sometimes happens when people talk about their "life flashing before their eyes" during a near death experience. Perhaps some of those times are when an exchange happens.
