Doctors have begun treating a new type of sleep disorder called sleep-mailing. The term refers to people who send e-mails while they are still asleep.
One 44-year-old woman discovered she had the embarrassing disorder when one night she e-mailed her friends invitations to a lavish party - while still sound asleep.
Having no memory of the incident, she was stunned when she began receiving RSVP's.
Another woman, Joelle Park, also discovered she had the condition when she e-mailed her boss on her Blackberry while she was sleeping. She was shocked when he confronted her about it the next day.
"My boss said 'Why are you e-mailing at 3 in the morning?' I looked at him like 'What are you talking about?' It happened a second time, but it was complete gibberish numbers and letters during that time," she said.
Doctors have pointed to sleeping pills as the possible culprit to these and other nighttime activities.
"These people have no proper judgment," Dr. Carols Schneck said. "They can't get up, they see their environment, they have no judgment, no inhibition - and that's the problem."
When Anna Ryan sleeps, she raids the refrigerator leading to a 60-pound weight gain. Another sleep disorder patient, Carrie Paps, actually drives in her sleep.
Paps recalled, "I got up. I drove to my office. I was fully clothed. But I have no memory of doing this."
One way to stop such behavior is to use a motion detector, which can be found at any hardware store. Put it in your bedroom and hook it up to an alarm, so you'll wake up before you do something you may regret.
Also, your doctor may recommend treatment at a sleep disorder clinic to help you get to the root of the problem, so you can sleep peacefully.
