Somnambulism, often referred to as sleepwalking, is a fascinating blend of two words from Latin origins: "somnus" meaning sleep, and "ambulare" meaning to walk. It describes the curious phenomenon where people walk or perform other activities while not fully awake. It’s both a medical term and a source of folklore, adding an element of mystery to the human experience.
If somnambulism were a person, it would be that unassuming neighbor with an unexpectedly adventurous side. By day, they blend into the crowd, but by night, they could be scaling mountains or taking moonlit strolls, driven by an enigmatic inner compass that even they aren't fully aware of.
The understanding of somnambulism has evolved from ancient myths about spirits controlling the human body to a more scientific perspective. Initially seen as a supernatural event, it’s now recognized as a sleep disorder. This shift from mystical to medical highlights changing perceptions of health and the increasing reliance on science.
While somnambulism doesn't feature in well-known proverbs, it’s inspired tales like those of the night walkers and moonlight wanderers. Phrases from antiquity may not have highlighted it by name, but the legendary "moon madness" surely pointed to it.

In the 19th century, sleepwalking was linked to mesmerism, a form of hypnotism. The case of Maria Marten, famously murdered in the Red Barn, saw somnambulism raised in court to explain mysterious actions and memories, a testament to its grip on the imagination of the time.
