For example, if the room is too hot, dry, or the sleeping position is not suitable, such as pressing your hands on your chest, which affects your breathing, and drinking too much water before bedtime, and having a distended bladder and urine, you can also have some nightmares.

When a child has a nightmare, parents should wake him up as soon as possible and comfort the child by saying, "This is a dream, not real, don't be afraid". Wait until your child is emotionally stable before putting him to sleep.

Medications are generally not required**. If your child wakes up from a nightmare, his heart rate and pulse increase, usually within 1 minute. After the seizure, it is difficult to wake up in the early morning of the next day, and it is often accompanied by sleepwalking.

It should be distinguished from nocturnal seizures. Consult a neurologist as soon as possible for diagnosis. Frequent nightmares are often caused by physical and mental fatigue, excessive excitement and restlessness before bedtime, emotional stress or spoiling.

Please go to the psychological counseling clinic for psychological **, you can take a small amount of sedative drugs as appropriate before going to bed under the guidance of a child psychologist, such as diazepam, pediatric times, for several nights. You should avoid watching scary movies and TV shows and listening to scary stories. Symptomatic treatment should be given to those with psychological stress and physical triggers.

When the nightmares are removed, they usually don't recur frequently. In addition, as we age, the onset of nightmares naturally decreases or stops.
