Yes, quochick, we are fragile indeed, but that is not all we are. It's hard to say who will be there when we 'arrive'. One time, in meditation, it seemed that a crowd was there; but, another time, it was just a lowly 'receptionist' who was the first greeter that I saw in a given situation. I've seen a man in heaven on his own homestead in the country, as if in another century. He liked being mostly alone, and being visited infrequently. It was all arranged for him. "God" even talked to him, from the sky, right into his own head.
I think it is, indeed, possible that we have multiple 'selves' in the afterlife, each with different likes and dislikes, different past experiences, etc.
I used to think that my own personality was quite fixed at one point in my life. I would never have imagined that it could change so radically, that I could change so radically. If we are as creative as we must be, as resourceful as human beings must be...it would not surprise me at all if 'heaven' turns out to be quite the fantastic place.
Anything and everything is possible there, as far as I can tell. The most consistent message I have received, if true, indicates that this area is an incredibly comforting and nurturing place. What lies 'beyond' it I do not know. But there are plenty of opportunities to be 'alone' too, if that is one's preference. In the great 'out there'.
