Control can sometimes be an illusion. But sometimes you need illusion to gain control. Fantasy is an easy way to give meaning to the world, to cloak our harsh reality with escapist comfort. After all, isn’t that why we surround ourselves with so many screens? So we can avoid seeing? So we can avoid each other? So we can avoid truth?
We construct fairy tales and we accept them. Our minds concoct all sorts of fantasies when we don’t want to believe something.
Heaven may be a fantasy for the credulous and the afraid. But I can give you a map reference for hell.
