My mum sleepwalks...
...not just walking, but talking and acting quite rationally. It's often quite difficult to tell whether she's awake or not- you can hold a conversation with her, and the next day she'll remember nothing of it. A few of the things she's done this year:

-Christmas eve, knowing we're going to grandma's the next day and taking the dog, she comes downstairs with the task of "sorting out the dog" ready to go. This involved over an hour sitting at the kitchen table, counting ever dog-poop bag she could find and sorting them by colour.

-Coming downstairs and watching whatever my brother and I have on TV, completely blank, and then going back to bed.

-Getting up, making (and drinking) a cup of tea, eating any biscuits in sight, and then going back to bed. (Think the Vicar of Dibley for this one, she's always waking up in the morning surrounded by biscuit wrappers and not knowing that she'd eaten them. This annoys her as she's on a diet.)

-(When I'm at university) Phoning me up, talking for over an hour about anything and everything, and then hanging up, forgetting the conversation, and calling me again the next night to tell me the same things again.

-I had to share a room with her this Christmas, and although she was asleep she managed to talk incessantly about Scrabble all night. My aunt said she could hear her through the door.

Mum reckons it's due to the medication she's on, so she's been going to the doctor to change it. Shame really, I'll miss it.
