So how do your characters "get taken out of themselves"? What are the triggers for them? What kind of music and/or books do they pursue to help them get the most out of life? What kind of music, to name one example of an escape trigger, does your character's world appreciate?
How do your characters treat others who get in the way of their escaping for a bit? Do they become grumpy, perhaps at odds with their normal reactions to people? And those who desperately need to escape for a bit (they're ground down, under a lot of pressure etc), what happens to them when they can't get taken out of themselves for a bit? Just how far can they go before they crack?
