There's a well known border line between facts and assumptions. And that border line sets the difference between knowing something and supposing something, between common sense and delusion.. It's simple as that, there's Cue and D1 on the one side of the border, talking from scientific point of view about facts, while on the other side of the border there's Free and Abnaxus who's talking about their beliefs based on their personal experiences, in other words speculates.
I wonder that Doc1 haven't mention the term "psychosis" already to you Abnaxus. And don't get me wrong, I'm not trying to mock or insult you, but that's like the default diagnoses for your case. Psychosis means that a person has trouble telling what is real and what isn't, as you do.
Hallucinations are very realistic to the people that have experience them and that's why they can't figure out if they're real or not. Here's a quote from the dictionary: "Hallucinations are false or distorted sensory experiences that appear to be real perceptions. These sensory impressions are generated by the mind rather than by any external stimuli, and may be seen, heard, felt, and even smelled or tasted."
Your examples are not unique and lonely, there's thousands and thousands of people that have experienced this or that. But you have to be aware that it is only your subjective trip, it all comes from your personal experience, from your own brain. And that cannot be real for anyone except for you until there's proofs and facts. Now, there's been thousands and thousands of subjective telepathy experiences, don't you think it's a bit strange that no one ever got to prove any? After so many years of testing with all the modern scientific methods? Same as in Free's example, there's thousands of people that have used this ayahuasca, how come that no one have a single evidence or proof about "remote viewing"? Doesn't that explain things by itself?
And if we talk about possibilities, yes, there's endless possibilities philosophically speaking, but that has nothing to do with the reality. If it comes to philosophy, it's possible that we're all in matrix, that there's a life after death, that the aliens rules the world, etc... but what are we talking about? Or I should better ask, what are you talking about?
