I understood 'night terrors' was just a newfangled name for nightmares.
REM Behavior Disorder
For most people, dreams are purely a "mental" activity: they occur in the mind while the body is at rest. But people who suffer from REM behavior disorder (RBD) act out their dreams. They physically move limbs or even get up and engage in activities associated with waking. Some talk, shout, scream, hit, punch, or fly out of bed while sleeping! RBD is usually noticed when it causes danger to the sleeping person, their bed partner, or others they encounter. Sometimes ill effects such as injury to self or bed partner sustained while asleep trigger a diagnosis of RBD. The good news is that RBD can usually be treated successfully.

Two entirely different disorders, that happen in two different stages of sleep.
Nightmares happen in REM Sleep, Night Terrors happen in Slow Wave Sleep.
Nightmares have “dream recall”, Night Terrors don't.edit on 7/3/2012 by defcon5 because: (no reason given)
Night Terrors
Night Terrors Symptoms: Sudden awakening from sleep, persistent fear or terror that occurs at night, screaming, sweating, confusion, rapid heart rate, inability to explain what happened, usually no recall of "bad dreams" or nightmares, may have a vague sense of frightening images. Many people see spiders, snakes, animals or people in the room, are unable to fully awake, difficult to comfort, with no memory of the event on awakening the next day.
Night Terror or Nightmare?: Nightmares occur during the dream phase of sleep known as REM sleep. Most people enter the REM stage of sleep sometime after 90 minutes of sleep. The circumstances of the nightmare will frighten the sleeper, who usually will wake up with a vivid memory of a long movie-like dream. Night terrors, on the other hand, occur during a phase of deep non-REM sleep usually within an hour after the subject goes to bed. This is also known as stage 4. (A link to a sleep stages chart can be found on the navigation bar to the left) During a night terror, which may last anywhere from five to twenty minutes, the person is still asleep, although the sleepers eyes may be open. When the subject does wake up, they usually have no recollection of the episode other than a sense of fear. This, however, is not always the case. Quite a few people interviewed can remember portions of the night terror, and some remember the whole thing.
