There's a woman in Canada named Celina Myers who posts security cam videos of herself sleepwalking around the house, and two of them have on TikTok.
In one she carries on conversations, puts "food" on the table, and suddenly rushes outside into the cold . . . until her husband shows up to rescue her.
In the other she's the "hostess" of a pool party. She goes into the kitchen to get drinks and then heads outside and tosses them into the front yard. That one also features a stranger who happens to be walking by on the sidewalk.
