I have only done this once before in a french hotel, I walked down a flight of stares and fell asleep next to the elevator woke up at 2 in the morning. I researched what causes sleep walking and the main cause was an unfamiliar sleeping environment, so I shrugged it off assuming the hotel was unfamiliar and the cause of my walking. I locked myself in my room so I couldn't leave for the rest of trip. Well I randomly started sleepwalking again. Today I woke up on the living room floor at 4 o'clock in the morning, which is on the other side of my house and a floor bellow my bedroom. I was in my house so it's completely familiar to me. I don't know what I did last night or where I went, and worried I'll do it again tomorrow night. Has anyone had trouble with this? or know how to stop it?
