Quizplus · Accepted Answer

Sleep is considered an altered state of consciousness because it is different from the typical waking state of consciousness. While some areas of the brain may become less active during sleep, others become more active. Additionally, dreaming during sleep involves complex thinking processes. While conscious experience of the outside world is diminished or absent during certain stages of sleep, it is not completely shut down.
