Night terrors strike children, usually between the ages of 3 years and 8 years. They rarely occur in older children, adolescents and adults. In both adults and children, night terrors may be caused by unsettled psychological conflicts, upsetting events or tiredness.
Night terrors are distinctly different from the much more common nightmares, which occur during REM sleep. Night terrors are characterized by frequent recurrent episodes of intense crying and fear during sleep, with difficulty arousing the child.
