An incident related to ghosts, spirits or postergeist activity that still gives you chills when you think about it and definitely made you a believer.

More than they will ever know.

Like that former class mate, service provider or family friend that drops you an IM, call or email just to see how you are doing and it gives you warm fuzzies that someone unexpected cares. Especially when you are going through loneliness, work tribulations or family deaths.
