Have you ever woken up to find food crumbs or your sheets, even though you don’t remember waking up to snack? What about waking up on the living room sofa when you vividly remember going to sleep in your bed? You may be a sleepwalker.

Sleepwalking, also known as somnambulism, is a sleep disorder that involves waking up and walking around while in a state of sleep. A sleepwalker might even perform more complicated activities such as cooking, eating, getting dressed, and driving. In some rare cases, a sleepwalker may even engage in unusual behaviours such as climbing off the window or urinating in the wardrobe.
