Nightmare

A nightmare is an unpleasant dream that can cause a strong emotional response from the mind, typically fear but also despair, anxiety and great sadness. The dream may contain situations of discomfort, psychological or physical terror. Sufferers often awaken in a state of distress and may be unable to return to sleep for a small period.

Nightmares can have physical causes such as sleeping in an uncomfortable or awkward position, having a fever, or psychological causes such as stress, anxiety, and as a side effect of various drugs. Eating before going to sleep, which triggers an increase in the body's metabolism and brain activity, is a potential stimulus for nightmares. Recurrent nightmares may require medical help, as they can interfere with sleeping patterns and cause insomnia.

Etymology

The word "nightmare" derives from the Old English "mare", a mythological demon or goblin who torments others with frightening dreams. Subsequently, the prefix "night-" was added to stress the dream-aspect. The word "nightmare" is cognate with the older German term Nachtmahr.

Nightmare (song)

"Nightmare" is a song by American band Avenged Sevenfold released as the lead single for their fifth studio album, Nightmare.

Overview

Lyrically, "Nightmare" deals with an individual who is damned for his wrongdoings on earth. The song is sung from the point of view of a resident of hell, who may have once been a living person too, mocking the other character and pointing out that it's his own fault he's in hell. It is their first single released without former drummer The Rev, who died on December 28, 2009. The song was released digitally on May 18 and 21, 2010 on the US and worldwide, respectively, on iTunes as well as an animated lyric video on YouTube, which received over 275,000 plays in 24 hours. A preview for the song was released on May 6, 2010 on Amazon.com, but was removed soon after for unknown reasons. However, on May 10, 2010, a 30-second audio uncensored sample was again revealed, but this time at SoundCloud.

"Nightmare" was nominated for Best Single at the Kerrang! Awards 2010, but lost to Liquid Confidence by You Me At Six. The song is also one of Avenged Sevenfold's best known, and had been certified Gold by the RIAA.
