What is the theme in Shoeless Joe by W. P. Kinsella?

Imagination, dreams, and reality make up another theme. Shoeless Joe is a wish-fulfillment, fantasy novel in which the dead come back to life, dreams come true, and old wounds are healed. It asserts the primacy of imagination over the demands of practical life. For example, Ray makes no attempt to get out of his mounting pile of debt. To all outside observers (except for his loyal wife, Annie), he is heading for disaster and his only practical option is to sell the farm. But Ray is one of the least practical characters imaginable. He insists on following his dreams and making them into reality.
