What does "Of Mice and Men" reveal about dreams and aspirations? Give an example with a specific character.

In Of Mice and Men by John Steinbeck, Steinbeck wrote about how dreams can make people blind of reality. An example of this is Lennie and his dream to have a big famr and take care of the rabbits. His dream makes him blind to see what reality is because he is so set on his dream of having a big farm that he is ignorant of his surroundings. He is always too busy daydreaming to realize what is really going on around him.
