Living people release energy, especially when experiencing a traumatic or emotional event. This energy can
be recorded by the environment. Some people, who are sensitive to this information, can then pick up on,
read these impressions of past events and feelings which have been stored in objects, buildings, and the environment.
Place memory is an old recording. It can't react, or interact with you, the way a ghost can. There is no consciousness involved. However, it's critical to understand that that place memory is made by the living. And that means that you person who created it could still be alive and well, living in Cinncinatti. It cannot be created by the dead (although I did find one case where they used that place memory as a kind of energy store they could draw on).
Perhaps the easiest way to think of it is as a case where the environment acts like a camcorder. If the conditions are right (involving sufficient repetition, environmental factors, and/or really strong emotions), then events can get recorded. People sensitive to this information (like psychics) can later play back what was recorded, like with psychometry. In these cases, there is no ghost, simply an old rerun of the past. It won't interact with you and the story always remains the same one. Not a lot is known about the actual way place memory is stored, but the recordings themselves seem to have an electromagnetic component.
So, what can you do about it? It's your choice. You have three options:
