Description

Some people have difficulties in getting a good night rest. A possible cause is the occurrence of nightmares. Nightmares can be so intense that people wake up screaming. These types of nightmares are also called 'night terrors' to emphasize their intense character. Another way in which sleep can be distorted is by sleepwalking. Although this behavior, that is often seen in children, is not dangerous in itself, it might be a good idea to secure the stairs by placing a fence.

Normal

A lot of people are active during the night. People can keep on turning in their sleep or talk in their sleep. Occasional sleepwalking in children can be somewhat troublesome, but not more than that.

Abnormal

Some people are so active at night, that they become a problem to themselves and to people they live with. There are several sleep laboratories in the Netherlands. Here the behavior during sleep can be studied. This might provide a solution to the problem..
