“Once, I woke up in the middle of the night to the sound of my bedroom door creaking open. I could see the outline of someone standing there, but when I turned on the light, there was no one there. The door was still slowly closing, as if whoever or whatever had been there was leaving.
Even creepier, my Nest fire alarm had illuminated in the corridor, sensing movement, but there was nobody there. Still gives me chills thinking about it.”
