Your dreams and imagination evolved as a view into another universe. As with the current beliefs, you cannot decipher technical information – no words in books, no details of how devices work, so even if you can describe things you see from another place, you could not reproduce a working version.
Now how do you convince others that the things your are seeing are really happening without being labeled insane? And how could you use this information to benefit yourself or others? Take a peek into the multiverse to see how other versions of yourself have solved these problems…
If our universe is being simulated on somebody’s desktop computer then yeah maybe, but if you were going to simulate a whole universe wouldn’t you at least have a decent random number generator to prevent easily-detectable patterns?
