Locke's vision/dream of Horace

Locke has another dream/vision in "Cabin Fever." This time, he meets Horace Goodspeed of the Dharma Intiative (he was first seen in Ben's flashback last season in the episode, "The Man Behind the Curtain"). He is chopping trees down to build a cabin for himself and his wife, Olivia. He cuts down a tree, then it reappears needing to be cut down again. This is a reference to The Myth of Sisyphus (click the link for more info). It's like Horace is stuck on a loop, doomed to repeat the same task over and over again. At the end of each loop, Horace's nose bleeds.

Horace tells Locke "You gotta find me John...and when you do, you'll find him (Jacob)." He then says "He's been waitin' for you a real long time man."

Also, the Dharma logo on his jumpsuit is for the Arrow station.
