What's that movie with a surreal golden tree appearing from time to time? [closed]

I once watched a movie of which I only remember a few things... The most present memory is this huge golden tree... Or at least I think the tree itself was golden. Then scene in which this tree appeared was golden, too. The sky was golden, the lights, there were golden particles and I think there was a man crawling around the tree...

This scene appeared several times in the movie, maybe 4 or 5 times... Unfortunately I don't remember the plot... Another thing I remember that it was a rather sad, dramatic movie. I also remember a woman lying in a bed, maybe she was deathly ill, I'm not sure about this. There might be the possibility that this woman and her illness was very important, there were often people visiting her.

I'm not sure about the ill woman, but I definitely remember this bizarre, surreal scene of a tree surrounded by gold.

I hope someone knows which movie that was, because I'd like to watch it again.
