The Eastern philosophies, Hinduism in particular, teach that this world is maya, that is to say illusion. That what we think we see, hear, feel, taste as reality, isn't really there. The world you know, the family you love, the girl or guy you adore, the kids you're so proud of, the house, car, boat, job or career that define you, none of it is real, it's all a figment of your imagination, a dream. Perhaps the figment of a mass imagination, or mass hallucination. If there is a mass to imagine or hallucinate that is.
If it is a mass imagining it would explain why the illusion goes on when the individual imaginer, you or I, pass away and move on. Of course the other possibility is that the illusion passes away with us. Which opens up more questions, for instance, if all this is a figment of your imagination, a dream, and ends when you pass away or wake up, how is it that the illusion apparently goes on, the rest of us continue to live, and we remember you, while knowing that you're gone? Why am I still here after my grandfathers, grandmothers, father, brother, and a girlfriend, anyone or all of which one would think could be the dreamer, have passed away? But then as I said above, I may be the imaginer, the dreamer. Those who've passed away simply left. No longer part of the dream, and it all ends as I pass away, waking up.
Another possibility, we're all living in our own illusions, and our illusions interact with other illusions randomly. That doesn't seem likely, but... Enough for now, thoughts or comments anyone?
