What happens to you when you die?

[Welsh cake]

I'm simply using my imagination to conjure up what I would want to happen when I die. You honestly don't do the same? Sometimes I also day-dream about what it would be like to have certain super powers or if I were rich. How is this any different?

Simple, one is a fantasy, the other is reality. Anyone can envision a dream that has the best-possible-case scenario, it takes a bigger person to face up to what is real, irrespective of whether it's comforting or not, because he/she will live their lives accordingly. Dreams have to be practical in their goals, based upon reality, that is, achievable within the confines of your limited abilities, time and resources... otherwise it's all a pointless exercise of mental masturbation.

Hoping, wanting and wishing doesn't make it any more or less possible, but it is possible right?

No, from empirical evidence and observation it's quite the contrary, its biologically impossible, there is no repository for our thoughts, memories and personality after death; without a living brain what is there left to support or sustain your consciousness?

How about this: Do you hope/want/wish there is an afterlife... of some kind... or no? If so, what do you think of? If not... why?

Yes and no, depends how long this afterlife that you propose is, existing *forever* as the quadrillions of years go by would quickly become monotonous, you'd outlive the universe in its current form and there wouldn't be anything to look forward to, or anything new to experience, you'd go insane longing for death in the cold void of space; you're hoping for the exact nightmare that many religious nutjobs hope for us, a living hell. I could never be so twisted as to wish that possibility, however improbable, upon anyone.

This would be true if this life were in a finite universe like the one we live in now but God is infinite so if we are with him there dosn't need to be any limit to the experiences we will have.

That demonstrates how little you know about the universe, especially when you make absurd claims about a deity whose nature by your omission is now so transcendentally complex, therefore is beyond your finite knowledge to make claims about in the first instance. In any case, neither you nor me are in any position to start shouting the odds over the scale or magnitude of the observable cosmos, we simply don't know enough about it to determine its absolute figure going by a base of ten or even in the scope of quantum mechanics. There are so many unsolved problems in physics regarding empirical phenomena lacking clear scientific explanation over dark matter and dark energy, which both apparently make up the bulk of reality at one point or other, that we can't claim the universe is either 'finite' or 'infinite', both labels are oversimplifying and asinine when you consider we still lack a clear understanding of the universe's ever expanding size.

Infinity, unlike cosmology is just a man-made concept, it can't be achieved or characterized or even falsified. If pressed, I prefer to call this universe we exist in "Transfinite". At least those are cardinal/ordinal numbers that are larger than all finite numbers, yet not necessarily absolutely infinite.
