I believe there is an explanation for everything, even if we can't explain it now... someday we will. that explanation might be paranormal.
Remember a long time ago mentally ill people were demon possessed. Electricity was considered by some to be the work of the devil. To some paranormal experiences are from the devil. Paranormal means beyond what is normal. The things we have today were beyond what was normal 200 yrs ago. So maybe 200 years from now we can explain these things. Just because it can't be explained doesn't mean it didn't happen or that the devil is behind it.
