how does (The Giver) end?

i read a book called The Giver. This book is about a kid called Jonas, he lived in a small community, it’s a weird community that the people in it never seen the outside world before, they don’t have feelings, they can only see black and white, they all get same thing for everything. They’re mostly like clones. But once jonas got the most important job in the community called (the receiver) which he gets the outside world knowledge passed down to him from the giver, them two were the only one who have real emotions and real world knowledge in the community since the beginning they got this job. Jonas found the life is boring to stay in this community, and he want to help these people in the community know the real world knowledge, he also wanted them to enjoy the fun of real world. So he decided to escape and search for a real world community.

As Jonas escaped, he brought Gabriel, one of his family unit with him that he discovered he could transfer his knowledge to him. They been through really tough real world weather as they escaped, in the end they were very very weak, and they saw a sled and slide down the hill, they heard people celebrating christmas and warm light and loving each other, then the story ended.

I think they died. Because if there really were a village down the hill, then i think they would have discover it/hear people’s voice earlier before they even sat on the sled, but they didn’t. So i think they saw those things happening because they started to pass out, and visualized their dream happened.
