Imagination.

In class we watched two episodes of the twilight zone. The first episode, The Lonely was actually my favorite. A man (corey)sentence to another planet for murder (self defense) becomes desperate to get off the planet.Astronauts visit every three months to supply him with food and necessities. One of the head astronauts brings him a box with a robot to act as a female companion. As time goes by the he falls in love with the robot and treats her as his partner. When the astronauts come back to release him of his sentencing, he will not leave without the woman (robot). The astronauts are convinced he has lost it because they know she is just a robot and she cannot come along. The astronaut ends up shooting her in the face to show Corey she was not real.

In the second episode Walking Distance Martin is grown business man who ends up returning to his old neighborhood. He feels as though nothing has changed since he left. At one point he runs into himself as a child. He also finds his parents who think he is crazy because the son they know is old about 10 years old.
After running arounf town like a mad man, his father comes to Martin and tells him that he must go back to where he came from or he'll mess everytyhing up for the younger martin. Martin ends up returning to his time but learning that he must enjoy his life.

With both episodes imagination is clear in that Corey thinks the robot is a real woman and Martin thinks hes back in time. Corey only feels that she was real out of desperation for a companion. It is only when the man shot her that he was brought back to reality and saw that she was not he thought. Martin on the other hand, one could argue that it was all his memory and mind playing tricks on him.
