Hypnagogia
Hypnagogia
Hypnagogia (pronounced: /ˌhɪpnəˈɡoʊʒə/) is the experience of the transitional state from wakefulness to sleep. The term was coined from the Greek words "hypnos" meaning sleep and "agōgos" meaning leading or inducing.
Etymology
The term "Hypnagogia" comes from the Greek words "hypnos", which means sleep, and "agōgos", which means leading or inducing. It was first used in the 19th century by psychologists to describe the phenomenon of the transitional state between wakefulness and sleep.
Description
Hypnagogia is characterized by a variety of sensory experiences that occur as a person is transitioning from a state of wakefulness to sleep. These experiences can include hallucinations, sleep paralysis, and lucid dreaming. The hallucinations can be visual, auditory, or tactile and are often vivid and dream-like. Sleep paralysis, a state in which a person is unable to move or speak, can also occur during hypnagogia. Lucid dreaming, the ability to control one's dreams, is another phenomenon that can occur during this transitional state.
