One night about a year ago me and a friend went to the mall to eat at the Chinese Buffet (called China Town). All the other stores were closed except for the buffet. The rest of the mall was dark and empty, so after we ate, me and my friend decided to wander about and enjoy the quiet. We didn't see anybody else in the mall after leaving China Town.
We stopped and started to goof off at a small play area at the opposite side of the mall.
Around the play area was a Sears, a fabric store, and an empty store that had gone out of business.
We goofed off, told funny stories of experiences we had there when we were in high school, and finally after slap "fight" we sat on a giant toy worm. We were just chatting when I saw something in the reflection of the window of the empty store. My friend turned to see what I was looking at and then it disappeared. We saw what looked to be an elderly person in green sweats (like the kind that had elastic around the ankles) and a white sweat shirt with the same color green stripes. It looked as though it was mopping.
We looked around to see if perhaps an employee was still in the fabric store. We didn't see anybody. We went back to China Town and told the manager, whom we are friends with, about it and he came to look around with us. We called out into the fabric store and peeked into the empty one but couldn't find anybody who could have given off the the reflection.
After we left and tried to find something out online but couldn't find any information on the mall except for how many people had owned it. To this day we still chat about it and get chills up our spines.
