Then I learned about how the brain works
Ha ha, Rem, there you go again, thinking you understand how the brain works . . . even scientists and doctors admit they really do not understand how the brain works.
After 100 years of scientific research there is zero evidence of paranormal activity.
A scientist who claims that zero evidence of paranormal activity exists has never experienced or been exposed to paranormal activity.
I'm not sure where you get that imformation from, but there are alot of people with incredible experiences that would argue and staunchly disagree with you. For example, I have a close friend who showed me a video tape he recorded in an apartment he use to live in. The camera had an ultra-sensative night vision mode that shows light streaks zooming and darting across his livingroom, dancing and bouncing in and out of the walls and doors and windows, the (unplugged) television set, and (turned off) wall heater vent. Never saw anything like it before!
In my hometown of San Diego, in Old Town, we have the "Waley House". It is an old house, now a musuem, and is the only structure in all the US that is certified by the government as being truly haunted, because of the undeniable evidence indicating it is inhabited by spirits. Many local celebrities and so-called scientists have attempted to spend the night in the structure to disprove its haunting and have not been able to remain inside for more than a couple of hours because of the manifestation of "spirits" and their obvious resistence to anyone hanging out, as it were. The spirits literally drive out anyone who tries to spend too much time inside . . . so no evidence? Hmm . . . what do you want or need as evidence?
