Whenever gibran gets into a discussion regarding dreams and reality, what I always wonder is: "If so, then what? "
What difference does it make?
I think its important to have this part of us that questions and doubts everything, that is humble enough not to make absolute affirmations about the Real.
But still we seem to most often go back to this 'consensus reality', so we have to make the best out of it. Its also of benefit to "do our best" with dreams and psychedelic states, but there is an advantage in considering the consensus reality "more real" at least in the sense for example that one could attempt to fly in a lucid dream without serious consequences, but I wouldnt advice you to do that in consensus reality (at least take off from the ground first, you know
)
Who knows if there is another life or if this is a simulation with many tries. You could even use a fancy argument about a simulation where doing unhealthy things will actually get you 'points' for your future life... But are you gonna base your daily decisions on that philosophical thought? Personally I rather try to do my best in this life as if its the one and only reality. Sure I explore other states of mind such as dreams or hyperspace/psychedelic realms, and I wont make absolute claims about what they are, but I certainly use them always in relation to the 'consensus reality' and will have criteria from this realm as the basis of my own particularized and limited mode for whats reality.
I will use science as a great tool for exploring this reality, knowing its not the end-all but its very important together with all other sources of knowledge, each with their relative weight. Also try to be healthy and regardless of how convincing some experience is, if it doesnt lead to my and other's general health and development, I will not follow it.
And I would do this all regardless if our universe is a simulation or if it would fit the materialistic world view. So you see why for me it always makes me wonder what is the point of those arguments in the first place ?
