I solved a family mystery for my mom. I wasn’t allowed to play console video games during the week all the way until I was 18 but some nights I’d really be craving it so I would noiselessly creep through my house into my basement where I could play video games in peace. But once every 30 times or so one of my parents would need something from the basement and I’d quickly turn off the tv monitor, hide in the guest room and pray they didn’t turn on a light or notice the Xbox was on. One night I ducked into the guest room and hid behind the bed. To my horror my mom followed me into the room and turned on the lights. I was panicking so when she started digging through the closet with her back to me I made a run for it. I nearly brushed her shirt and if she’d seen me I’d probably have given her a heart attack. But I made it and kept going all the way to bed.
About 5 years went by and my mom said something like “you’re such a quiet walker” and I told her it was because of my basement trips thinking I had nothing to lose. My mom’s face went kinda solemn and when I explained she said “so there really was someone down there.” And she explained that she remembered that exact night and the feeling that there was a ghost in the room. Over the next couple days she’d stare into space and just say “I can’t believe you were really there.” She seemed to get over it but she probably checks empty rooms closer now.
