Hypnos is the Greek god of sleep in ancient mythology. He is a primordial deity, considered the personification of sleep itself. Hypnos is the son of Nyx (Night) and the twin brother of Thanatos (Death), both figures often associated with quietude and transitions of consciousness or state. He resides in a dark cave in the underworld where the sun never shines and where poppies and other sleep-inducing herbs grow.
In myth, Hypnos is depicted as a gentle and benevolent figure who can ease pain and bring rest. He is often shown as a young man with wings—either on his shoulders or brow—symbolizing his swift, unseen movement through the world. Unlike other gods, Hypnos was not feared but respected for his power to soothe and heal through rest. He also had a son, Morpheus, the god of dreams.
In esoteric thought, Hypnos can be associated with altered states of consciousness, meditation, lucid dreaming, and the liminal space between waking and sleep. Energetically, he correlates to the theta and delta brainwave states that facilitate deep subconscious work and spiritual insight. Hypnos’ essence invites surrender, renewal, and connection to the deeper layers of the psyche.
