When worlds collide

You live your life and make decisions,
based on your mind, what it believes in.
You have a problem - then you need solution.
That's when you turn to next dimension.
To know the world, you make a copy.
And in your mind you walk right through it.
Solution comes, some times it doesn't...
The "copy" changes, sometimes it mustn't...
The gap then grows, between the two.
The difference shows like red and blue.
And soon, one day it comes to end.
Which world wins - you will determine.
And if you've seen a "copy" winning,
then you would know these words true meaning:
"When worlds collide in one another,
the most believed will beat the other!"
