My shrink put the kaboosh on my very active fantasy world when he told me that fantasy is a world in which we are always completely in control. Having a fantasy is feeding your need to control and lessen feelings of helplessness.
That really irked me. So I asked him, "what's wrong with fantazing?" Absolutely nothing, he said, as long as you do not allow fantasy to feed unrealistic expectations and desires. Fantasy is one-dimensional. Life is multi-dimensional.
