Every day for a week, we would wake up in the morning to discover that my brother's room had been tied closed with a rope. Also, for five years I've been the only one in my family to hear random tapping noises that I'm pretty sure is Morse code, and my computer would blink on and off randomly for a year, only stopping whenever I tried to show someone or screen record it.
The tapping isn't just in my house, and once I told it to shut up and let me sleep, and it did.
