Well, I don't really know what to tell you. I thinkI answered a question similar to that and I think it might have been yours.
Here's the thing I _don't know_ what happens to us after we die. There, you and I are alike. As I've never lived in your head, I can't say anything about any visions you've had. But I can tell you with certainty that there is no one on this planet who knows where we go when we die. There are merely those who believe that they know and those who admit that they don't.
Apart from that, I don't know what to tell you. I mean, we're all human and we all need to find peace in our own way. I'd never question the validity of _how_ we find that peace. If a Buddhist can find peace in the notion that a loved one may have reached Nirvana, then that's great. Neither you nor I believe in Nirvana, but I do believe in its power as a concept to help people accept unfortunate realities.
I wish I could believe it myself. Nirvana, heaven, whatever. I mean, why not? Why not have the peace that your experience has given you? Do you presume to think that I wouldn't _like_ to see my loved ones again? I'm just as human as you - have the same joys and sadnesses. The only problem is that I'm 'cursed' with an inability to put my faith in things I don't believe. I don't really understand what makes you so hostile to that. Are you _threatened_ by the fact that I don't believe in heaven? I'm not threatened by the fact that you do...
It would give me great comfort to think that I had enough money in my bank account to live the rest of my life in comfort. I would love to believe that I'm actually independently rich. It's a good fantasy. I'd also like to believe that I have movie-star good looks and I stop traffic wherever I go. But then I have to accept, uncomfortable though it may be, that I'm just an ugly guy who has to slog through his work to feed his family. Facing up to unfortunate realities is an important growing and learning experience. Some of us merely do it in more detail than others.
