or the solar system wouldn't even exist if we really were inside some goliath matrix-style computer simulation, or if life really was just one big dream.
The technical term philosophers and scientists use for this is "non-veridical".... Meaning do all of those things inside your dreamworld really exist or have ever really existed once you have awoken from that dream??-- Obvious answer is NO, cos once you've 'awoken' it is only then will you realize that that dream shreds to dust when truly confronted with the reality of waking up from the illusion!
