We've been able to debunk about 90% of the cases we do. Overactive imagination, businesses seeking publicity, misperceptions, sleep paralysis, carbon monoxide, mold, infrasound, high EMFs, hoax. I was interviewed for the show Scariest Places on Earth about 6 years ago and it's fake. Also shows like Ghost Adventures use horrible protocols and feed people misinformation.
We look for normal explanations, and we don't use psychics or use "toys" like K-II meters, dowsing rods, ouija boards, oviluses, Frank's Boxes, etc. We dismiss orb photos, mists, and we're familiar with the different kinds of camera defects like long expsosures, etc. We tag sounds, cross check voice recorders and video, do control silences, and correlate data and personal experiences with other data.
In seven years I've only captured/experienced a handful of things we couldn't explain. It's not like on the TV shows where you're getting 20 things in one night or something on every investigation. Things aren't jumping out at you going RAAWR. I've never gotten anything on camera or video we couldn't explain away. But the few things we HAVE had happen are interesting enough that I want to continue to do it.
I believe that nothing exists outside of science, but there could be some things out of our current understanding of science. Thousands of years ago, everyone thought lightning was paranormal and now there's a perfectly normal explanation. If you study quantum physics there are things happening at the quantum level that would seem impossible. String theory which has evolved into M-Theory supports the existence of other dimensions. Maybe every now and then they crossover just for a few seconds and we get a glimpse. Maybe to them WE'RE ghosts.
