Is hypnos lullaby real

Hypnos' lullaby is a fictional concept primarily associated with the character Hypnos, the Greek god of sleep, from mythology. In various stories and adaptations, it's portrayed as a soothing melody that helps induce sleep. However, in reality, it does not exist as a tangible lullaby; instead, it symbolizes the calming and restful effects of sleep. Some may create their own lullabies inspired by such themes, but there is no actual "Hypnos' lullaby."
