How do dreams figure into Homepathic prescribing?

My dreamlife becomes very active and meaningful when I'm on the right remedy. The night I started on my first homeopathic remedy (nat mur) I began a series of dreams that, over a year and a half, followed the resolution of a bird phobia that I'd had for many years. It wasn't a very serious phobia but I tended to avoid pigeons and would have bad dreams where largeish birds were somehow oppressing me. They might be sitting on my head and shoulders and I'd be afraid to breathe. I hadn't gone to the homeopath for this reason though I probably had mentioned the problem.

I'm wondering what significance vivid, meaningful dreams have in homeopathy. Perhaps for some of us there needs to be a dream effect or it's not the right remedy? I am an artist, maybe that's a part of this. Other remedies have also had a dream effect, though none so incredible as the year and a half unwinding of the bird phobia.

Any ideas about the dream effect?
