If everyone died at once

Just thinking if there were a worldwide calamity, and humanity -- almost 8 billion of us -- all died at once. And let's also suppose there's an afterlife. Suppose that would be better than an individual dying alone. I mean, almost 8 billion of us floating up to some afterlife realm or realms. 8 billion bewildered souls in telepathic communication with each other asking where are we, what is this, where do we go? Be less scary than if one just died by oneself.
