So I've been looking forever for a specific fic.

Spock suddenly is not alone in his own head. There's a boy (Kirk) that he's able to talk to while they're both sleeping. Pretty sure Spock ends up talking his parents into going to Earth (but fuzzy on this part).

I know this isn't a whole lot to go on but i really wanna read it again :)
