6 of the most haunted places to explore in Seattle & Tacoma

How we know it's haunted:
The house, now home to a literary arts center named for a Seattle-born poet, was previously occupied by the Bonney-Watson mortuary and funeral home.

"We were doing an investigation there for "Nightline" about 10 years ago," said ghost hunter Ross Allison. "The film crew was following us around when we went into one of the rooms upstairs and all of a sudden all of our equipment was drained of power. Even the camera crew's equipment, they were able to catch what had happened just as their equipment started draining as well, very rapidly. We couldn't figure out what caused that."

Ross also said his crew was able to record some interesting EVPs, or, electronic voice phenomena, which are sounds found on electronic recordings resembling speech, but are not the result of intentional recording or rendering, and are often a sign of ghostly presence.

Ross said that at the time he was there, "they took us down to the basement, and in the basement they still had a coffin for an infant."
