Why this word is great
NOCTAMBULATION — [Noun] The act of walking while asleep; sleepwalking. From the Latin noct-, nox ("night") and ambulatio, ambulare ("a walking, to walk"). Unlike somnambulism, which clinically frames the phenomenon as a parasomnia, or noctivagation, which implies a conscious, wakeful roaming of the dark, noctambulation carries the haunting poetry of the body moving while the mind is utterly absent. It is the silent descent of stairs in absolute darkness, the hand performing cryptic domestic tasks by moonlight, the profound quiet of a house holding its breath—a fragile testament to the autonomy of the flesh when the spirit has departed to a country it will never recall.
