Whats your most responsive ghost hunting experience

During an episode of "Ghost Hunters", Jason and Grant, founders of The Atlantic Paranormal Society (TAPS), invited psychic medium Chris Fleming to accompany the team on the investigation of a home on Cielo Drive. Located in Hollywood, California, this road was the site of the infamous Manson murders of 1969, wherein cult members entered the home of starlet Sharon Tate and brutally killed her, her unborn child, and four of her close friends. This particular house, along with several others on the same road, is believed to be haunted by the ghosts of Sharon, her friend Jay Sebring, and the others. This area was also the location of a number of suicides, as well as Indian deaths and burials. The homeowner, Dave Oman, and his acquaintences report hearing footsteps and voices, and Dave awoke one night to see an apparition standing at the foot of his bed pointing towards the direction of the driveway. He didn't recognize the man at the time, but three months later while researching the area, he came across a photo of Mr. Sebring and identified him as the man who had manifested in his bedroom that night.

During the investigation, Chris decided to try out a new device that is currently all the rage in the paranormal community: a K2 (or K-II) meter. This handheld device is a special type of Electromagnetic Field (EMF) detector. An EMF detector locates and tracks energy sources, and picks up on fluctuations in electromagnetic fields in the surrounding environment. Because spirits are comprised of energy (since energy cannot be created nor destroyed) it is believed that when an anomaly is present, it disrupts this electromagnetic field. When you experience a cold spot in a haunted house, it is because whatever spirits are present need to absorb the energy around them in order to manifest (either physically or audibly.)

So the idea is that ghosts can actually communicate with the living by disturbing the electromagnetic fields that surround the K2 device. In the episode of "Ghost Hunters", for example, Chris told the spirits that they could answer his questions by making the meter flash twice for "yes" or once for "no". A previously inactive screen began lighting up with activity but only when he asked the questions. They even changed the batteries just to make sure the meter wasn't on the fritz, but fresh batteries produced the same results.

According to Grant:

"The K2 meter measures magnetic fields, and it's been specially calibrated for paranormal investigations. The theory behind the K2 meter is that if there's a spirit in the area, the K2 meter will pick up it's magnetic field. You can then train the spirits, supposedly, to intensify its magnetic field, therefore lighting up the lights on the meter."
