Help with finding a book?

I have been trying to remember the name of a book I read back I in the early 80’s. I can’t remember the title or the author :( I thought it was { the dream weaver }, but that dosent seem to be right.

I do remember lots of details… it was about a woman who’s father recently died, and as she was driving down the freeway, had a nervis break down and left her car and ran into the woods eventualy passing out.She is found by by a set of twins, one of which is mute and they take her back to their village…

Does this help?
