Sleepwalking is a disorder that causes people to get up and walk while they're asleep.

It usually happens when a person is going from the deep stage of sleep to a lighter stage or into the awake state. The sleepwalker can't respond during the event and usually doesn't remember it. In some cases, he may talk and not make sense.

How Loneliness and Sleep Are Connected

Loneliness and sleep problems have long plagued me, beginning at age 7 when my family moved twice within one year. Struggling to make new friends, my self-esteem plummeted, and the shyness I developed established a pattern of persistent loneliness.

You might also have the disorder if you're:

  • Sleep deprived
  • On a chaotic sleep schedule
  • Stressed
  • Drunk
  • Taking drugs such as sedative-hypnotics (which promote relaxation or sleep), neuroleptics (used to treat psychosis), stimulants (which boost activity), and antihistamines (used to treat symptoms of allergy)

Medical conditions that have been linked to sleepwalking include:
