I haven't smoken any weed, but I too have pondered the ramifications of an infinite universe. :-)
I like to think about infinity in terms of a personal dream world existing. Here's the thing. If we accept the premise that the cosmos contain an infinite number of universes with an infinite number of planets, it naturally follows that if a world is possible, it therefore must exist. It's like buying every possible number combination in a lotto. One of those tickets is a guaranteed winner. So if all the premises are true, we can naturally conclude that there exists a world where all your dreams come true. To visualize this in the simplest syllogistic form we have:
An infinite cosmos contains all possible universes with all possible worlds.
A world where all your dreams come true is possible.
Therefore, a universe exists that contains a world where all your dreams come true.
When we write down the argument this way, the flaws to the idea of a dream world actually existing stick out like a sore thumb. The main problem is that it assumes too much. It assumes, for example, that the cosmos is infinitely populated (it would be a non-starter to say that there is just empty space stretching out to infinity although this might be a possibility). It also assumes that a dream world is possible. There's no way of determining this. It's like the old ontological argument for God. If something is claimed to be possible, that does not make it so. It must be demonstrated to be possible first.
Lastly, I sometimes have trouble defining a world where all my dreams come true. I am here on this planet from this universe. If I exist on another planet, but with different thoughts and memories is that really me? How will my consciousness work? Can I achieve awareness in both selves? Do I have the same desires? If we can't even clearly define such a world, how can we go about proving that it is possible let alone that it exists?
These problems though don't subtract from the joy of partaking in this thought experiment. I fancy myself as the mad scientist tinkering with his creation in hopes of creating a perfect masterpiece. One day the world will behold my work and bow down in awe of its magnificence. Mwahahaha! Ok, I'm done. :^)
