I don't really have any explanation for this, as the place it happened has (after me doing a ton of investigating) no record of anything like this happening before. It was just another normal boring day at work. I run the office here and at the time no one else was here, just me catching up on work from my day off sick. It was around 2pm (Maybe the time has some significance?) I really don't know.
I heard a strange clicking noise coming from the office next to mine where meetings are held. I sat for a moment wondering if I was imagining it, but it got quite loud, so slowly I wondered over to the door.
Before I go on I will try describe the room best I can. Imagine a basic square room the door is in one corner of the room on the left so when you open the door it backs onto the left wall. On the same wall side as the door there is a double window that looks out into the showroom, on the right hand wall (opposite from the wall that the door backs onto) there is another window that looks outside and the back wall is just plain with no windows
So, the door was slightly open and even stood at the door I could feel how cold it was in there. I pushed it open only to see a tall black human like shadow hovering about half a meter from the floor just inside the room not far from the door. I looked straight at it and it just froze there for a couple of seconds, then at a very slow pace it floated from one side of the room towards the window that looks outside and vanished into the wall. As soon as it vanished the temperature totally changed.
Since this has happened the room has felt cold a few times and I have called out a couple of times, the most I have got is the clicking sound I heard in the beginning.
Again I have asked as many people I can if they knew anything about this or seen anything but no one knows a thing about it.
On writing this I'm wondering... Why are you here, what is it that's stopping you from resting?
