My husband is experiencing Night Terror since his childhood, when consulted then, doctor said once he grows up and after getting married these type of issues will be resolved. But this is something vague I believe. Sometimes he starts screaming in sleep, which begins in a slow note followed by high pitched screaming. Sometimes he behaves aggressively, beating limbs violently on bed or anyone sleeping beside him. In every such episodes he never remembers what happened. Please suggest what should be done. We have never found anything triggering such act.
