Something I noticed while reading Oedipus Rex was the amount of interpretation left open, even for a drama. In Trifles the characters were, more or less, set out; we were told by the writer where they stand, how they move, etc, but in Oedipus the characters can have any tone of voice, any type of body language, in other words, the actors and directors of a stage performance of this play can bend it to their own creativity, the only thing binding them is the dialogue and plot.

The point of the play which seemed to suggest the Oedipus Complex was not the plot, but the line that says (i cannot find the exact line) that amny men have dreamed of sleeping with their mothers, which, I believe, told Freud that this was not an isolated case but rather a common fantasy that was less repressed, and therefore less subconscious, than it is now. I do agree with Ioannis that the case Oedipus himself does not seem to be a true Oedipus Complex but rather an unfortunate coincidence.
