"Well, this is a problem, isn't it? I get hallucinations if i drive for 12 hours (takes a toll on me), or if my body temperature is really high. But because my experience is unique and unrepeatable, I can't claim that something i've experienced is universally true. That's the difference between belief and fact."
Yuri, your two examples involve non-normal, body imbalances. The experiences i'm referring to, are not due to unusual and extreme body states but happen during "normal" body conditions and wouldn't be classified as hallucinations by any psychologist worth their weight in education. For starters, check out Dr. John E. Mack, who was the head of the Harvard psych department.
And still taking the UFO and E.T. phenomena for example. When so many people in our times and throughout the ages have had experiences during normal body states with one, the other, or both of these, when does a skeptic actually open their mind a bit and consider, "hey, this could be possible true?"
Here's the thing about this, a number of scientists have stated that it's probable that there is other life in the Universe. Many have stated that it's also probably even probable that there is intelligent life in the universe. The odds in such a large universe are in favor of same.
However the mistake that a lot of scientists make in their human arrogance is thinking that we have physics all figured out in a big picture sense, and that more intelligent than us beings couldn't possibly have figured out how to travel extremely far distances in short times to be able to visit Earth.
That's a lot of assumption and largely based on mechanistic, Newtonian physics and to a lesser extent relativity-Einsteinium (yet, Einstein's theories allow for wormholes which can bypass the speed of light constant). What about the common postulation of different, but connected dimensions that go beyond our own> What about quantum physics which indicates that a particle can even be at two different places simultaneously (which btw, strongly implies a fundamental unity or oneness to the very core of reality)? You could argue, well that only applies to super small particles and we've seen no evidence of this happening at larger and denser levels of reality.
Well it's true we don't see it in nature, but what about the thousands of unexplained UFO sightings across the world. What about the numerous military and high political figures who have come forward and stated plainly, we were involved with secret knowledge of E.T.-human interactions.
At some point, "skepticism" (again, especially mostly with the majority of men) just becomes a synonym for close mindedness and stubbornness, and unwillingness to consider viewpoints different than ones own.
I get it, some folks just don't want to have belief system crashes. They are quite unpleasant. I try not to convince people of specific things (though i'm doing it a little with the E.T. thing) because i realize that ultimately, people need their own experience to really have their belief systems shaken up and rebooted. I have been quite skeptical towards these things, like E.T.'s, nonphysical reality, etc, but for whatever reason i've had numerous experiences which have contradicted my previous beliefs and skepticism, and after awhile (especially after the fear dies down) one's curiosity takes over. And a true scientist type, is nothing, if not curious...
Along those lines, i highly recommend one Robert A. Monroe and his books. He was also one sort of forced to change his beliefs by direct experience and ones he couldn't control and didn't consciously ask for. As mentioned earlier, the physicist Tom Campbell and he, crossed paths for awhile and to very interesting and mutually beneficial results.
Tom and his engineer friend, helped Monroe to design the audio technology called "Hemisync" which is quite interesting stuff theoretically and in an experiential way ; ) My wife and i spent our honeymoon at the Gateway Voyage program at The Monroe Institute in Faber VA. To say it blew our minds is an understatement.
What i really like about Monroe was that he wasn't in the business of pushing beliefs or dogma of any kind, but rather providing good tools to people to go out and have their own verifiable nonphysical experiences. The only belief he asked for others to consider was that we are potentially more than our physical bodies and he highly stressed physical world verification to prove this to self. For example, in the early days, the physicist Tom Campbell and his engineer friend Dennis, would be separated physically, told to go out in nonphysical consciousness states and meet up (they sort of meditated). It got to the point in their consciousness travels together that they started repeatedly corroborating specific data and information.
