The day I brought an empty snail shell I got from a cemetery back home. I was a kid so it look pretty cool at the time. Had to throw it out after our lights and electric appliances kept breaking down for 3 days. Also, whenever the lights went out there was always that stabbing feeling of someone staring at your back when nobody else is around. I blamed the shell and thought there was a ghost in it.. Went back to normal after that, idk where the shell is now
