what dream does george and lennie share?

Lennie and George share the dream about the rabbits (Lennie's dream) or the farm (George's dream).

In Chapter One, Lennie requests that George “tell about the rabbits,” which is his shorthand for “talk about how things will be for us in the future.” George paints a picture of the future – a picture he has obviously painted countless times before – in which he and Lennie have their own place on their own farm and “live off the fat of the land.” He promises Lennie that they will have rabbit cages and that Lennie will be allowed to tend them. Lennie repeatedly interrupts George as he tells this story, but insists that George finish it to the end.
