Movie Titanic: did Rose die in the end?

This is a dumb question, but who in here thinks that Rose died in the end of the movie titanic?

If you remember correctly, in the very end of the movie, it shows her pictures and she was asleep and then the ship came back to life and jack dawson was waiting for her by the clock and everyone was waiting for her and clapping.

I thought it was just a way for the movie producers to end the movie in a good way or she was just dreaming, but people tell me she died in the end in her sleep.

Any thoughts?
