What will happen to me when I die?

“Then there came—at first from very far off—sounds of wailing and then, from every direction, a rustling and a pattering and a sound of wings. It came nearer and nearer. Soon one could distinguish the scamper of little feet from the padding of big paws, and the clack-clack of light little hoofs from the thunder of great ones. And then one could see thousands of pairs of eyes gleaming. And at last, out of the shadow of the trees, racing up the hill for dear life, by thousands and by millions, came all kinds of creatures—Talking Beasts, Dwarfs, Satyrs, Fauns, Giants, Calormenes, men from Archenland, Monopods, and strange unearthly things from the remote islands or the unknown Western lands. And all these ran up to the doorway where Aslan stood.

This part of the adventure was the only one which seemed rather like a dream at the time and rather hard to remember properly afterward. Especially, one couldn’t say how long it had taken. Sometimes it seemed to have lasted only a few minutes, but at others it felt as if it might have gone on for years. Obviously, unless either the Door had grown very much larger or the creatures had suddenly grown as small as gnats, a crowd like that couldn’t ever have tried to get through it. But no one thought about that sort of thing at the time. The creatures came rushing on, their eyes brighter and brighter as they drew nearer and nearer to the standing Stars. But as they came right up to Aslan one or other of two things happened to each of them. They all looked straight in his face, I don’t think they had any choice about that. And when some looked, the expression of their faces changed terribly—it was fear and hatred: except that, on the faces of Talking Beasts, the fear and hatred lasted only for a fraction of a second. You could see that they suddenly ceased to be Talking Beasts. They were just ordinary animals. And all the creatures who looked at Aslan in that way swerved to their right, his left, and disappeared into his huge black shadow, which (as you have heard) streamed away to the left of the doorway. The children never saw them again. I don’t know what became of them. But the others looked in the face of Aslan and loved him, though some of them were very frightened at the same time. And all these came in at the Door, in on Aslan’s right. There were some queer specimens among them. Eustace even recognized one of those very Dwarfs who had helped to shoot the Horses. But he had no time to wonder about that sort of thing (and anyway it was no business of his) for a great joy put everything else out of his head. Among the happy creatures who now came crowding round Tirian and his friends were all those whom they had thought dead. There was Roonwit the Centaur and Jewel the Unicorn and the good Boar and the good Bear, and Farsight the Eagle, and the dear Dogs and the Horses, and Poggin the Dwarf. “Further in and higher up!” cried Roonwit and thundered away in a gallop to the West. And though they did not understand him, the words somehow set them tingling all over. The Boar grunted at them cheerfully. The Bear was just going to mutter that he still didn’t understand, when he caught sight of the fruit-trees behind them. He waddled to those trees as fast as he could and there, no doubt, found something he understood very well. But the Dogs remained, wagging their tails, and Poggin remained, shaking hands with everyone and grinning all over his honest face. And Jewel leaned his snowy white head over the King’s shoulder and the King whispered in Jewel’s ear. Then everyone turned his attention again to what could be seen through the Doorway. “

Revelation 20:11–15 ESV

11 Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. 12 And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. 13 And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. 14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15 And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire.
