was watching the discovery channel today "the top 10 unexplained mysteries".
no all documentaries are scientifically sound, accurate, or even trying to tell you the truth. for instance:
faith healing
is a known practice of trickery, combined with the power of the placebo effect. hell, i'll even teach you how to do it.
aliens
may exist, but
alien abductions
are heavily associated with sleep paralysis. scientific study has even shown that you can produce mental images of the standard grey alien in lab conditions, using a rather weak electromagnetic field (equivalent to that of about a hair dryer)
finally the after life was number 1
people get all the standard out of body experience, tunnel vision, hallucinations, memory flashes, etc, everything associated with nde's in centrifuges. it's a reproducable result. but these people don't die, they just lose circulation to the brain.
