What does Simon find when he is walking in the forest?

If you are talking about Chapter 8, Simon finds a glade where he is able to sit alone in the sunshine and meditate. It is also in the forest that he see the boys Jack and Roger hunt down the pig and kill it. The head of the beast speaks to him, but does it really or is it only his inner self advising him of what he needs to so. The pig tells him that interfering with the others will make them come after him. Simon needs to get away from the other boys.
