Slipping in Reality

POTENTIAL SPOILER ALERT: I am starting to add comments in my lists in lieu of reviews/notes so beware of the potential spoilers. I will try to keep them to a minimum because I get it. 

Alternate realities, time-travel, parallel dimensions, multiple timelines. Heck, there may even be some reincarnation thrown in for good measure. You know, living in our our own world but also not.
