What’s the creepiest thing to ever happen to you?

I was home alone taking a shower when I heard the sound as if someone closed the front door and a while after that a sound of switching the light on in the toilet room. I was convinced some family member came and expected them to come to the bathroom to wash their hands. Nobody was coming in though. I finished my shower, got dressed and was ready to welcome them but as I opened the door..no one there, everything was quiet like before. But the light in the toilet room was turned on. I turned it off and waited, at that point I was sure there was no one there but I opened the door just to be sure. 😆
