Sleepwalking is a common sleeping disorder where the sufferers walk around or perform other complex tasks while ostensibly asleep

One of the rarer sleep disorders, Idiopathic hypersomnia sufferers can’t seem to get enough sleep.

Parasomnias are unnatural events or experiences that interrupt sleep and incorporate undesired feelings, perceptions, movements, or behaviours.

Night terrors (or sleep terrors) are events or experiences of intense fear, resulting in screaming and physically flailing – all while still asleep.
