Once, when I was in my 20’s, I slept walk.
I had left some 3.5” disks out for my Amiga 500, and when I woke the next morning, each and every label had meticulously been peeled off the disks without tearing and reapplied upside down.
I tried to do the same task when I was awake to another disk and utterly failed not to damage the label. People can do weird stuff when they sleep walk.
Also, apparently I can talk when I sleep walk, according to one girlfriend.
I think your girlfriend reversed the labels as a joke.
Either her or the cat. Cats are sneaky and have bizarre senses of humor.
I carried on a conversation for an hour with a girlfriend, at around two in the morning and never knew I did it ... LOL ...
Yeah, I sleepwalked as a child, and I would go to the bathroom, hold conversations, navigate myself downstairs to the kitchen to get a snack, etc.
One time, after I had recently switched bedrooms, my mom found me sleeping on the floor in my old, empty bedroom, in the spot where my bed used to be :)
I almost burned my house down whilst somnambulating. I put food on the stove, and sat down to watch the tv which wasn’t on. I woke up when the smoke made me start coughing. Ambien. I had outgrown the problem, but the damn Ambien brought it back. People have been pulled over sleep driving!
