THOSE HORRIBLE NIGHTMARES!

Nightmares are disturbing dreams associated with negative feelings, such as anxiety or fear. Nightmares are common. They may begin in childhood and tend to decrease after about age 10. However, some people have them as teens or adults, or throughout their lives.
Until age 13, boys and girls have nightmares in equal numbers. At age 13, nightmares become more prevalent in girls than boys.
Nightmares seem real, often becoming more disturbing as the dream unfolds. But nightmares usually are nothing to worry about. They may become a problem if you have them frequently and they cause you to fear going to sleep or keep you from sleeping well.
Nightmares are referred to by doctors as parasomnias — undesirable experiences that occur during sleep, usually during the stage of sleep known as rapid eye movement (REM). You’ve had a nightmare if:
-Your dream wakes you
-You feel scared, anxious, angry, sad or disgusted as a result of your dream
-You can think clearly upon awakening, and can recall details of your dream
-Your dream occurs near the end of your sleep time
-Your dream keeps you from falling back to sleep easily
Children’s nightmare content varies with age, typically becoming more complex. While a young child might dream of monsters, an older child might have nightmares about school or difficulties at home.
