This is not the scariest experience but I think people in the area would like to know about it and I can't find any stories listed for this location so I have decided to post it.
A few years back, I think it was the summer of 2009, my husband, daughter and I went to Marietta Ohio for a weekend get away. We saw that a ghost tour of downtown was offered so we put that on our must do list.
We met the tour guide, a self-described paranormal investigator, at the fountain downtown around 9pm. There were 10 or so people on the tour. The guide was great, she took us inside the historic hotel, which we were excited to hear was reputed to be quite haunted as we were staying there, and walked us past a few other buildings with their own spooky tales.
The last stop was an old theater, which she took us inside. She told us that it had been unused for many years but a civic minded group was working to restore it. It had originally been a vaudeville style stage theater and later a cinema. Of course it seems all theaters have to have an array of ghosts and this one was no different. She enthralled us with tales from days past and with recent accounts from those working on the current refurbishment. Then we were allowed to wander through the seats and stage.
I fell back and was telling my daughter they had done quite a job setting the mood; I actually thought I saw something when we first walked in from the lobby. She asked me if it had been in the section on the right about 5 or 6 rows up. I was startled because that is just where I thought I had seen something. She said she had thought it looked like a middle aged woman that was a very pale white. I had not been able to see enough details to guess age or sex but agreed that what I saw was a pale white.
We tried to eavesdrop a little on the others to see if it sounded like anyone else had seen it, but everyone was just commenting on how "cool" and "creepy" it was. Maybe it was just the lighting and the power of suggestion, but one of the reported ghosts was thought to be that of a wealthy female benefactor who had been very involved in the theater.
Neither my daughter nor I like to draw attention on to us, so we did not mention to the guide what we thought we saw, but now I wish we had.
