the land of nod

The phrase "the land of nod" typically refers to a state of deep sleep or a dreamy, hazy state of consciousness. It is often used as a metaphorical expression for being in a tranquil or peaceful sleep. It originated from the biblical story in the Book of Genesis, where Cain, after killing his brother Abel, is said to have been banished by God and settled in the land of Nod, which is often interpreted as a figurative place of wandering or exile. However, its more colloquial usage today is primarily associated with sleep.
