LOTR Missing scene?

[TooManyNoneQuestions]

I've just rewatched the 3 Lord Of the Rings films for the first time in years and am convinced there's a scene I remember that wasn't in any of the films - am I going crazy?

A group of them go into a forest controlled by elves (?) to heal / get help. They leave after a short time to find out a much longer time has passed out in the real world - years I think. Several battles have been fought, people died etc while they rested in the forest.

It could be from a different franchise altogether but does anyone else remember the scene?

There is a time "dilation" (is that the right term??) in the book. Sam gets in a muddle about it. I can't remember if it's in the films. Haven't seen them in years. Good shout for the winter evenings.

Thanks. I did start to read the books but didn't get very far they were a bit confusing. It's possible I got it from there though.

It might be one of the Narnia films?

There is a scene in the book when they're in Lothlorien forest and what feels like a short visit actually takes a month. It's not clearly covered in the film though.

It's not in the films, including the extended versions.

You must be confusing it with a different framchise.

Not from the LoTR films.

That’s not LOTR.

Yeah, although it's not exactly the same. In the end of Lion, Witch and Wardrobe they are shown as adults who go on a hunt, back through the wardrobe and become their young selves again. Then in Prince Caspian they return to Narnia and find ruins that were their old castle, and eventually work out that although only a year or so has passed for them, hundreds of years have passed in Narnia. There's also a separate scene where the two girls ride into the forest to get help so you might have conflated them, or a different franchise again.

Definitely no scene like that in LOTR films (although as a pp said there was something similar, but not as extreme in the book) though although I suppose again you might have mixed up the 'going to the elves to seek help' bits (in both Riverrun and Lothlorien) with the mines of Moria, where they go in expecting to find a working mine and lots of dwarves but it's all abandoned with skeletons, and then mixed that with what you remembered from the book and conflated it all together in your mind?

Thanks everyone! I have watched the Narnia films so might have got it from there. Of course it's equally possible that I made the whole scene up completely in my head (I was either at uni or a new mum when I last watched LOTR so either way, quite busy / sleep deprived).
