6. The elevator kept opening and slamming shut on its own
“I did night security in a very old grain exchange building that had been converted to mainly lawyers offices. A lot of the building was remodeled but the grain exchange floor and vaults had been preserved and at the end of one hallway behind the main lobby I was stationed in there was an elevator that was original to the building that nobody ever used.
I was sitting at the desk one night around 3am when I heard the ding from down the hall that meant someone had called the elevator. There wasn’t suppose to be anyone in the building except me so I switched to that camera feed and the elevator doors were wide open which is only suppose to happen if the call button has been pushed. I wait a few minutes being pretty freaked out but the doors stay open and I never see anybody. The doors are suppose to close on their own shortly and these ones are stuck open. I start to think that someone is in the building and holding the door open button from within where I can’t see on the feed so I have to walk down there to check it out.
As soon as I get near the end of the hallway where I have a clear view of the elevator the doors close. I just kind of stand there feeling really uneasy and decide to head back to the desk and leave a note for the maintenance crew. About 10 minutes after I get back to the desk it happens again. Ding and then the doors roll open. Except I had the feed up so I know that nobody was there to press the call button. I wait and again the doors stay open. So I walk back down there and as soon as I walk into view they close.
