A cautionary tale: Last year our friends (visitors from Hawkes Bay) were about to embark on a family holiday in Vanuatu and stayed with us in Auckland before their departure the next day.
During the stage called rapid eye movement (REM) sleep, the eyes move quickly and vivid dreaming is most common. Each night, people go through several cycles of non-REM and REM sleep. Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (called N3 sleep) early in the night. When physical movements such as kicking, flailing, or getting out of bed occur during REM sleep, it is part of REM behavior disorder and tends to happen near morning. As people age, they have less N3 sleep. This is why sleepwalking is much more common in children and young adults.
During this stage you are paralysed to prevent you from acting out your dreams, but it is during the much deeper sleep that sleepwalking takes place. It is a curious, paradoxical state. The brain is active enough for you to move, but not so active that you wake up.
