Positively for sure? Most cannot say without proof. However, I travel and film various locations, I am an Urban Exploration Filmographer by hobby, and have been to several places. I have heard and seen the unexplainable, even after searching vigorously for the source or what could have caused the anomaly, some was never explained, even with advanced cameras, lighting, computers, and more technology, we could never debunk some of it. I'll share a few of the shorter instances, so I don't write a book.
Abandoned science facility, shut down by EPA, entered one of the buildings and immediately felt slightly off, heard what sounded like a dog's bark. I had two lights and a camera, all with over 50% battery, I know that my crew and I were alone. The bark was easily heard by all of us, as if the animal or human imitating it was very close, after hearing it, my equipment went dead. I had to battery swap everything, we stood there, looked at each other and listened for it again, but nothing. We still searched thoroughly afterwards to no avail. It still chills me a bit, due to how audible and real it felt, even to find nothing inside or out. There were various specimens and remains in the building from its history, it was sealed too well for anything but birds to get in.
Abandoned apartments, closed for some time but this section wasn't damaged, just unlocked but closed up. Looking around for a mini explore video, entered a building that was set up like townhouses, two to a building. Looked around, undamaged but kind of dirty as expected, after entering the second floor we stood around, still for a pan shot and heard a knock followed by a louder bang. We closed all doors upon entry and were not moving or talking when this happened. The noise was from the first floor kitchen area, only place with hard flooring, the cabinets had been closed and a broom that was in a corner had been toppled over. We opened the cabinets, but didn't touch the broom, no airflow, no power, no open windows or doors and we were on the second floor, we only captured the audio.
That is two, but I have more, just want to keep this short. All of these are backed by audio and/or video evidence, as well as my crew. What does anyone else have? I may list more at a later date if asked, curious to see what others have. To answer your question, yes, I believe.
