Feelings and emotions are difficult subjects for people to deal with. With time and age and insight you begin to realize that just because you have certain feelings that are perhaps not mainline it doesn't mean that you are crazy. Furthermore, even though we have certain fantasies, it doesn't mean that we always play them out in real life. An active fantasy life is probably a good thing. Working these things out in play (or in prose) probably contributes in an important way to good mental health.
