Becoming a civilian again after being in the military was interesting. Simple things felt weird all the time; I kept feeling like I had to show my ID to buy groceries, stuff like that. But probably moving to the East Coast (NoVA) from Colorado in 2002 was the biggest. I was in absolute shock at the price of housing, hours of commuting every day, and most of all, how horrible the people were. Mean, rude people, angry all the time and intentionally threatening on the roads. Being there made me cry a lot in the first year.

Tough question, but I found The Gone World by Tom Sweterlitsch to be very disturbing. It really freaked me out in places.
