A Reddit user with the nickname "mira1834" posted a video from a surveillance camera several days ago, filmed at her place of work - in a trampoline park. Country and city are not specified. The user works as a security guard on the night shift. The recording was also made at night. The footage shows a small translucent ball-orb, which purposefully moves from left to right.
The most curious thing is that this ball has something behind it that looks like a smoke trail from its movement. This trail dissipates very quickly, but it can be seen. “That night when I was at work, at about 12 o'clock, I heard strange sounds. I felt very uncomfortable. It was something like the creak of a chair, but when I looked out the door, of course, there was no one there and the sounds instantly died down,”mira1834 comments on his recording.
“After that I decided to check the recordings from the CCTV camera. This building is empty and dark, no one was there. I found on the recording that moment in time when I heard unusual sounds and there was this object. It doesn't look like dust, it doesn't move like that and doesn't leave such a trace behind it. It seems to be an object made of energy."
The post collected quite a few comments. Someone assumes that this is a camera glitch, another that it is just a drop of water sliding off the lens. However, the author of the video assures that there was not a drop or any condensation on the camera lens, it was dry. There have also been suggestions that this is a ghost in such an unusual form.
