If you've encountered a ghost, experienced paranormal activity or any strange event you can't explain, then maybe paranormal investigators can help. It could be something strange or unexplained occurring in your home or workplace, a friend's place, or somewhere else you've visited. Or it could be a paranormal-looking photograph, a very odd video, or a spooky sound recording.
If contacted by you, paranormal investigators in your neighbourhood, could then arrange a site visit, which sometimes is enough to work out what's going on. Beyond that, they may conduct a full site investigation. If you're elsewhere in the world, they may be able to offer you helpful advice by email and/or refer you to others nearer to hand who can assist you more directly.
Paranormal investigators can generally work well with psychics, as they are essentially investigating the same entities, each producing results by different means.
