What is the creepiest "glitch in the matrix" you've experienced?

Source.

The front elevator in my dorm was always on the 6th floor when me and my friends went to call it to our fooor, it wasn't until nearly the end of the year we realized: that elevator only went to the 5th floor. We stopped using it after that and only used the stairs lmao



Not sure if this counts, but it's what I've got. Lol.

When I was a kid, we lived in apartment that was haunted with something. My mom, who grew up in the woods of Louisiana, was born with an clear layer of skin over her eyeballs that they had to cut away. In her town, they said she was born with a "second sight" to see things that others couldn't. She used to see sh.it all the time in that place...and I did too, other family members too. Anyway, the whole time we lived there, without fail, I had a nightmare EVERY Saturday. Wasn't the same nightmare, but creepy enough that I started to try and stay awake on Saturdays. Stopped once we moved out of that building. My mom still freaks me out sometimes with the stuff she sees though. Lol. Has nothing do with the matrix but creepy enough for me!
