My dream of you

A clearly Christian genre also fed into the development of the immrama. This is the vision tale: The story of a man or woman who experiences a vision, often in a dream, of the afterlife, of heaven or hell. The dream often takes the shape of a journey, and the dreamer is conducted, sometimes by an angel, through the Christian and moral otherworld.
