I was a ghost hunter, long before it was cool.
I spent a lot of time in the dark, I toured some really cool historic places, met a lot of interesting people, and saw some weird stuff.
None of what I did was science.
I learned a lot. I learned history, I learned building construction (the basics), I learned how heating and plumbing works, and I learned a lot about people.
The most important thing I learned is that no matter what I saw (or think I saw) I have no proof, and I have nothing that I could write up as a scientific paper to submit. That's just the way of the world.
I have discovered that Infrasound is a bigger deal than people suspect, and may have effects on humans that are just now being explored. Those effects line up with many of the phenomenon attributed to ghosts.
I have learned that some people get really mad when you tell them their house is not haunted.
My interest in the paranormal led me back to college where I have taken a number of science classes (Oceanography, Marine Biology, Environmental Science, and Geology 1). These have left me with complete confidence in the scientific method. Scientists have open minds about a great many things, but for those things to be accepted they need to be solid, repeatable(verified) data, a cross-section of physical evidence (collected samples), and it should lead to a predictable outcome.
This hasn't changed my beliefs, it has reshaped them.
Today it's not about seeing ghosts but WHY are ghosts seen. To me this is the operative question, and it saves me from freezing my butt off in an abandoned jail at 2:00 AM.
As for dying? I was 10, the nurse gave me an overdose of medication (she was new) that stopped my heart. I was gone for 10 minutes until they could re-establish sinus rythmn. One second I was vomiting and the next I was on a table with my shirt off and an air mask on my face.
That's all she wrote.
