I have had three encounters at my building where I work. Have seen the same man 2 times and a black dot about the size of a nickel bouncing around in the air in my warehouse. After each encounter it has become cool even chilly near the encounter area.
Is there a website I can go to, to find out if anyone has passed away here or near by?
The man is young, aprox 5'8" dark brown short neatly parted hair, and shirt is blue and white striped. I have not seen his face except from the side. He ducked down in front of my front desk station, the next time he was standing in my computer room with his back toward me staring at our new camera monitor. He is only there for a split second then gone.

There is no website like that but I would suggest that you contact your local newspaper and ask them to help you as they would probably have a news story somewhere with that particular location of having someone's death happen. If this is an older building maybe you could ask one of the workers who has been there a long time at that job if they recognize this person at all from your description. He might not have died there but worked there instead.
