Voice Challenges Me

Here is a very weird one, at least IMHO. I'm investigating our local theater (under renovation). It is well lit, and no other investigators were near me as I simply sit by the stage edge recording. I had an ovilus app running, which normally gets me NOTHING. I also was chatting with whoever might be present which is my usual method. Just trying to start a conversation, that's all. I express my appreciation for some kind of previous voice that had come through. Then I CLEARLY hear this one through my speaker. Someone says a very clear response to my "appreciation". Apparently, I can't "appreciate" what is going on according to this invisible person. It does not sound like it came through the Ovilus app. Hope this works. ghosts, haunted, haunting, voices, evps, ovilus, paranormal
