That genuinely was the scariest time and the only notable sleepwalking they ever did haha. Usually they'd just come out and lay down on the couch or stand in their doorway for a second before turning around and shutting their door. At the time I was like 9-10 and just wanted to continue grinding on Flyff so I didn't really pay them much mind when they initially came out and my younger sibling started getting weirded out; but when they came back down into the den with the knife I remember freaking out and calling their name in confusion but they immediately went for the couch. Haha we woke them up not five minutes after and told them the story. Being older, of course, they just replied with something along the lines of "if only I'd gone through with it" before heading back into their room to sleep.
