Exercise of the Psyche
Just as our body can become stiff and unstimulated by lack of exercise, so our soul – our mind and emotions – can become atrophied through lack of use. Often everyday life may not challenge us enough, may not face us with fears, or be such that we encounter new environments. Dreams are an area of human experience where a phenomenal range of experience can be allowed. Because dreams contain deeply felt emotions and fresh experience, such as mentally stimulating environments and situations, they can truly be thought of as exercise for the soul.
