I just like feeling anything...

A nightmare is an unpleasant dream. Nightmares cause a strong unpleasant emotional response from the sleeper, typically fear or horror. The dream may contain a situation of extreme danger, or sensations of pain, bad events, falling, drowning, being raped, becoming disabled, losing loved ones, encountering unpleasant creatures or beings, being murdered, caught, attacked, being chased, eaten, squashed, stuck or burned, becoming physical causes such as a high fever or being face-down on a pillow during sleep, or psychological ones such as psychological trauma or stress in the sleeper's life, or can have no apparent cause. If a person has experienced a psychologically traumatic situation in life—for example, a person who may have been captured and tortured—the experience may come back to haunt them in their nightmares. Sleepers may waken in a state of distress and be unable to get back to sleep for some time.
