What are Tom's dreams?
Tom's dream in The Glass Menagerie is basically to run away from the alleyway apartment and the oppression that his family has him under and be free to write poetry, read literature, and experience the adventures that he sees in the movie theatre where he goes to escape from everyday life.
Tom is a born poet, which is a huge contrast from his rogue-type job at the factory, where darkness, and a harsh environment are the rule. Instead, Tom imagines beauty, adventure, color, and freedom. These are his mechanisms of escapism and is meant to contrast his reality versus his fantasy.
