While I was browsing, I saw this article. Its title, "Emailing while Asleep" caught my attention in that it reminded me of my cousin.

My cousin, Glenn, used to sleepwalk. One time, we watched TV while he was sleeping. Thirty minutes later, we saw him walking towards the kitchen. We thought that he was really awake, so we never cared about it. Until, he went to the living room where we were watching TV. He was bringing with him a pail and a basin. So, we asked him where he was going. Then, he told us that he was going to wash his clothes. We were shocked because it was already 11pm. Finally, we found out that he was just sleepwalking since his eyes were closed when he did it.

Anyways, here's the full story of the article.

According to a case described in the medical journal Sleep Medicine, a 44-year-old sleepwalker logged onto her computer and emailed out party invitations to friends. Fortean Times magazine looks at this case and several other bizarre episodes of somnambulism. From Fortean Times:

The mails themselves were perhaps not up to the woman’s waking standard; each was in a random mix of upper and lower case characters, badly formatted and containing odd expressions. One read: “Come tomorrow and sort this hell hole out. Dinner and drinks, 4.pm. Bring wine and caviar only.” Another said simply: “What the…”

The writers of the report have dubbed this new variation of sleepwalking ‘zzz-mailing’. They say: “We believe writing an email after turning the computer on, connecting to the Internet and remembering the password displayed by our patient is novel. To our knowledge this type of complex behaviour requiring coordinated movements has not been reported before in sleepwalking. She was shocked when she saw these emails, as she did not recall writing them. She did not have any history of night terr­ors or sleepwalking as a child.”

Unlike simple sleepwalking, they argue, the activities the woman engaged in required complex behaviour and coordinated movement, as well being able to remember her login details. She had no memory of the events next day. It’s thought that the somnambulistic episode may have been triggered by prescript­ion medication.
