I've watched people flinch at these sounds, simultaneously, in locations where they could not receive visual cues from each other. At this time, I have no explanation for this. Nevertheless, I believe that telepathic communication can be valid. Most people who receive impressions psychically or telepathically, choose to describe them in terms of the five senses. Summary Different people perceive paranormal phenomena in different ways.
Some people are more attuned to visual imagery.
Some hear ghosts. Others sense emotions or energy, or other manifestations. However, there are unexplained noises and voices at some haunted sites. In time, perhaps we will find ways to use traditional and new measurement techniques, to detect the sounds that some perceive. More importantly, perhaps we'll find ways to communicate with the spirits that linger.
