Let's look at the history of the Trans-Allegheny Lunatic Asylum. Between the years 1864 and 1994, the grounds of this institution saw unspeakable conditions that put patients through hell; if only the walls could speak. But if you bring the right equipment (say a Ouija board), you might be able to just ask the ghosts yourself. I think they'd agree with me when I say the street they lived on, was a nightmare.
