Nightmares

Most teens have nightmares on occasion, but frequent nightmares can disrupt a person's sleep patterns by waking him or her during the night. Some things can trigger more frequent nightmares, including certain medications, drugs, or alcohol. And, ironically, sleep deprivation can also be a cause. The most common triggers for more frequent nightmares, though, are emotional, such as stress or anxiety. If nightmares are interfering with your sleep, it's a good idea to talk to a doctor, therapist, or other counselor.
