"Sleep or night terrors should not be confused with nightmares. A night terror causing one to awake in feeling of intense terror or panic. Young children suffer most from night terrors, but adults can also suffer from night terrors."
Night terrors are a type of sleep disorder characterized by sudden awakening from sleep with feelings of terror or fear. They typically occur during non-REM sleep stages and are more common in children. Night terrors are different from nightmares and the person experiencing them may not fully wake up or remember the episode.
Night terrors are worse than nightmares because they terrorize you in your sleep and can make you physically ill.
There is no exact science behind night terrors. The definition of night terrors is typically considered the extreme and amplified sequence of nightmares which cause trauma to the body and mind. Night terrors can occur from emotional and mental health problems arising from recent trauma in a persons life, even children. It is not the ONLY cause of night terrors. Some people will produce more of a certain type of chemical which helps regulate sleep and it can cause extreme nightmares (night terrors) It may also be a product of wild imaginations. Parents should also watch the content their children are viewing on television prior to their sleep to check for patterns. It is typically advised that a person should not watch television 1-2 hours prior to going to sleep as this interferes with REM sleep which may be another cause of night terrors
The symptoms that you described seem to indicate a condition known as night terrors. It is different than nightmares. Children have them occasionally, but tend to grow out of night terrors by about 10 years old. In adults, it is not normal and needs evaluation. I suggest you make an appointment for your husband with his general practitioner. He or she will guide you from there to the next steps.
They occur during REM sleep, usually in the second half of the night
I have the same problem. It is caused by stress when it all comes down to it. Could be from something in you daily life, or from night terrors or nightmares.
A nightmare is one of those dreams where, when you wake up, you thing "Oh, thank goodness. It was only a dream." Then you roll over and go back to sleep. Night terrors are dreams so vivid that you wake up thinking that the incident actually occurred, and may continue to think so until you are fully awake. Most people have them once or twice a year. If you are having night terrors regularly, you need to consult a professional and get some counseling. Frequent sleep disruptions are extremely bad for your physical and emotional health. Whatever you do, don't drink or take sleeping medications to avoid them. They do nothing to correct the underlying problem, and you will become dependent on the booze or meds to help you sleep, just adding another layer of problems.
Topamax can potentially cause sleep disturbances, including abnormal dreams or nightmares, which could lead to night terrors in some individuals. It's important to discuss any concerns with your healthcare provider.

Gerard has said in interviews that Sleep was inspired by his troubles sleeping while the band were in the writing process at The Paramour Hotel. He said that he would have night tremors (or night terrors) where he'd convulse, feel like he was being strangled and would wake up unable to breathe. You can hear recordings of him talking about these night terrors and nightmares throughout the song.
