I've posted my stories before, but what the heck. May be all new people reading this time.
I work part time in a radio station. It's in an old building with the stations, a 2000 seat theater, ballroom (now offices) and bowling alley (now storage area)
A few years ago, I'd be down in the production room and see a face peeking in the small window of the soundproof door. I thought I was just being paranoid and would shake it off. Then my PD mentioned that "the face" never bothered him until it laughed at him when he screwed up on a cut he was working on and started cussing. That was when I realized I had seen something. I was talking with another girl who was there (upstairs) when this happened to my PD so she told me the whole story and how she'd seen it too. Between her version and the PDs version matching up, plus me being able to finish descriptions she started, we knew we weren't crazy. After that, I paid a little more attention when I saw the face. I could tell it was an old woman, lots and lots of wrinkles, gray hair. That year, they had a psychic come in on the morning show for one of the stations. She went down and said it was an old cleaning lady named Lily.
Not long after that I got roped into running a hockey game for the local minor league team. The broadcast was using a cell kit, so I could talk to the play by play guy during breaks since it was through the phone line. At one point during the game, there's all this beeping . . . you know the sound when you hit redial? It was exactly like that but a MUCH longer string of numbers. Just kept going for about 20 seconds (which is an eternity on air) He goes to break a couple minutes later and asks what I did. I told him nothing, I was on the other side of the room and thought he hit the kit or something. He said he stretched the mic and was nowhere near the kit, and no one else was by it either. It had never done it before, and never again.
My worst was a few years ago. I was down in those production rooms, finishing up some work. There's an office around the corner from the room, maybe 10 steps away, if that. As I'm getting my stuff put away, I hear a very loud noise. Imagine the sound of someone desperately pulling at a doorknob trying to get out of a locked room. That's what I heard. LOUD. And considering the only other person in the building at the time was one floor up and on the opposite side of the building, I freaked.
Late at night you hear odd noises from the 3rd floor. No one's up there at that time of night, but you hear huge thuds. I always say it sounds like a team of acrobats up there, practicing. I'll also hear on the 2nd floor the very clear footsteps of someone walking down the hall or opening the men's room door (that needs WD-40'd desperately) but when I peek around the corner, no one's there.
And there's a man I see all the time. He'll stand outside the studio and watch, sometimes I catch him walking ahead of me when I go down the hall. I've been seeing him for 4 years. I was talking not too long ago to one of the guys at work about it when talking about strange things happening there. I described the guy (I can give pretty good detail on him, I see him so clearly) and he asked when I started seeing him. Apparently the man that trained him (but quit long before I started working, so I never met him) passed away around the time that I started seeing this ghost. . . and matched my description.
