An Occurrence At Owl Creek Bridge

From the story An Occurrence At Owl Creek Bridge the theme of the story to me is reality vs illusion. I think that because In the story Peyton Fraquhar was a a good worker from the south. He was tricked into doing the wrong thing. With that being said he was hung to death. By him listening to a friend he was killed. He never got to go home to see his wife again.
A symbol in this story is the log floating down the river. Its the symbol because a log floating by fast and just get down the creek. He was being hung but it seemed like for real for him to die. Just like the log it was taking to long. To see the log is a sign of  Peyton Fraquhar his self. Both were taking too long. He should have been dead, the log should have been down the creek. both were taking way too long.
