The Glass Menagerie--Reality and Nonrealistic

DUring the course of the glass menagerie the reader is included in the narrations led by Tom, a character in the play. He starts out by distinctly describing the way in which the play will be carried out and then proceeds to describe how his memory is not all realistic. That is what struck me. Since when is memory not realistic? Then it hit me, sometimes when one remembers an event their mind can formulate their own perception of what happened. One can make an event more happy or sad or any other emotion. Tom did not so much say this but alluded to it in his very long, wordy speech. SO memory is what makes the play have a dream like quality and make it non realistic. While some part of it have been remembered correctly so they are in fact real. I think the memory is what gives the play its dramatic effect which makes it able to be on the stage and engage the audience with the dramatic ironies added onto the play.
