In Of Mice and Men, Lennie is affected by George's dream. When life gets frustrating, Lennie desires to hear George retell his dream. George has a dream of owning his own farm and farm house. When he retells the dream for Lennie, he always includes the part about the  rabbits. Lennie dreams of having rabbits on their farm. Lennie desires to pet and tend to the rabbits. 

George often retells this dream just for Lennie's sake:

George repeats, at Lennie's request, the story of how they are someday going to get out of the lonely life of itinerant farm laborers and buy a piece of land where they can live by working their own small farm together.

Lennie loves this dream. He anticipates with joy the day that he and George can buy their own farm and raise rabbits. Although George gets frustrated from time to time with Lennie, he still takes the time to retell the dream to cheer Lennie up. 

On the ranch they are now working on, George and Lennie meet 
Candy. Candy is getting old and works as a handyman around the ranch. Candy hears about the dream and desires to be a part of the dream. He asks George if he can pay him his life savings and join George and Lennie on their new farm. Candy feels that he is getting too old to be any good to anyone. He feels it is just a matter of time before he is kicked off the ranch for being too old to work. 

 Candy is the old, disabled ranch hand who is helpless to stop the shooting of his dog and who knows that he too will be banished when he is no longer useful. 

Indeed, Candy dreams right along with George and Lennie at the possibility of having a dream farm of their very own. He commits his savings of 350 dollars to buy the farm. 

Then Lennie breaks Curley's wife's neck and George has to kill Lennie. No doubt, Candy is upset when George kills Lennie. Of course, he feels bad for Lennie, but he also knows that George will cancel the dream. After killing Lennie, George does not desire to follow through with his dream of having a farm of his own. Without Lennie, the dream just seems to not matter.
