Ethereal Realm

This is a metaphysical expression for the afterlife. The ethereal realm is the place where we would live after death, and it is believed that our soul is floating there while astral projecting. The ethereal realm is the name given to an unknown parallel world, the world of happiness and enlightenment.

Dreams feel real while we're in them. It's only when we wake up that we realize something was strange. (Inception)
