Jellico,TN Post Office Haunted?

I've lived in Jellico my life, and I've always heard that the Post Office in downtown Jellico is "haunted". Now I don't know if you have ever witnessed anything supernatural, I hadn't. Until I went in there a few weeks ago. I didn't believe the rumors of hearing foot steps and voices in the top floor, or the sound of mail carts being rolled when no one was there. So one night me and a few of my friends decided we would wait till dark and go in and see if this so called "legend" had any truth behind it. So we walked in and everyone was silent. I'll admit it I was a little shaken by even walking in there so late. Nothing happened at first but then all of a sudden we heard the foot steps, the silent murmurs. It freaked us out. Then we began trying to talk to it. This was not successful.(the first time we went) right before we ran out if the post office we heard the mail cart roll across the back room. Eyes wide we ran to the car. We drove around the back and parked for a minute. Plan as day you could see some movement. I don't know how you feel about being in the post office at night, but I don't even like being in there in the day. I get a strange feeling. I really believe there is a sprit or something haunting that place. It may not be violent (as far as I know) but I will do some more observations and post more about the Post Office and other "haunted" places around the Jellico and Newcomb area. Thanks for reading and more updates shall come soon.
