Sleep is an American doom metal power trio from San Jose, California, United States. The band earned critical and record label attention early in its career. Critic Eduardo Rivadavia describes them as "perhaps the ultimate stoner rock band" and notes they exerted a strong influence on heavy metal in the 1990s. However, conflict with its record company contributed to Sleep's breakup by the end of the decade. The band reformed in 2009 and has played sporadic live dates internationally since. In 2018, Sleep released their comeback album, The Sciences, on Third Man Records, to critical acclaim.

A nightmare, also known as a bad dream, is an unpleasant dream that can cause a strong emotional response from the mind, typically fear but also despair, anxiety, disgust or sadness. The dream may contain situations of discomfort, psychological or physical terror, or panic. After a nightmare, a person will often awaken in a state of distress and may be unable to return to sleep for a short period of time. Recurrent nightmares may require medical help, as they can interfere with sleeping patterns and cause insomnia.

A dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. Humans spend about two hours dreaming per night, and each dream lasts around 5–20 minutes, although the dreamer may perceive the dream as being much longer.
