For me it's Stephen King's Dead Zone, about a man, Johnny, who wakes up from a coma with psychic powers.
(SPOILERS)
He's working as a tutor for a high school boy later on and he tells his student not to go to the graduation party as the restaurant will burn down. No one believes him, but the boy and about half the class come to an alternate party at the boy's house because they're scared. The rest of the class goes to the restaurant.
Johnny and the boy's father are playing cards while chaperoning the alternative party and a radio announcement interrupts to say that the worst fire in the state's history has broken out at the restaurant, and almost everyone there is dead.
I haven't explained it that well, but for some reason ( and I've read it a few times) I literally get goosebumps at that bit. Every time!
Anyone else have this or just me? :o
