I was in my bedroom with my door cracked open, just listening to music when all of a sudden, my door flies wide open. It was my cat coming in. After that jump scare, I start to get out of bed to close my door, when I had come to the door to close it, I saw a shadow person. It was just standing there in the hallway, right in front of me, with its left hand on the light switch. For a split second when I blinked the hallway light shut off and the shadow person was gone again when I turned the light back on.
