Motion-Activated
I lived in a house that was built in the 1800s. It survived countless disasters and had seen some stuff. One of the previous owners had two sons who took their lives. A lot of strange things would happen.
Our animals—a dog and parrots—would wake up from their naps and follow something with their heads just as they would follow me if I walked around. Before I switched rooms in the house, my brother had a room that he refused to sleep in, as he would hear voices.
He slept with my parents until the day he got my old room. There was also a whole floor we wouldn’t use. I slept in the attic and would pass through the unused floor to get to my room.
I had a motion-activated light that would go on as I would walk the stairs to that unused floor. It would switch on in the middle of the night while nobody was walking under it. Story credit: Reddit / suspiciouspalmtree
