|"Is this all real? Or has this been happening inside my head?"
The subject of this article is a real-life person, company, product, or creative work that has been mentioned "in-universe" in a canon source. The Harry Potter Wiki is written from the perspective that all information presented in canon is true (e.g., Hogwarts really exists), and, as such, details contained in this article may differ from real world facts.
Somnambulism (also known as sleepwalking) is a sleep disorder. People that suffer from this disorder leave their bed, without waking up, in a state of low consciousness and perform activities that are usually performed during a state of full consciousness, such as walking around.
In the early 19th century, a young Beatrix Bloxam overheard her aunt telling The Warlock's Hairy Heart, by Beedle the Bard, to her older cousins. She became, reportedly, "paralysed with horror" and heard the full "disgusting story", as well as details of a ghastly affair concerning her uncle Nobby, the local hag and a sack of Bouncing Bulbs. The child was traumatised by the shock: she spent a week in bed and developed the habit of sleepwalking back to the keyhole in which she had overheard her aunt, every night, until her father put a Sticking Charm on her door at bedtime.
During the 1991-1992 school year, a prefect that caught Harry Potter wandering the corridors after curfew commented that he wished he could believe Harry was merely sleepwalking before docking him three house points and sending him back to Gryffindor Tower.
Behind the scenes
- The Somnambulist Charm, a spell that exists in the script for the film adaptation of Harry Potter and the Prisoner of Azkaban, induces somnambulism in the target. It would have replaced the use of Mobilicorpus to transport an unconscious Severus Snape in the novel.
