Communication in dreams

[Faerie_witch]

I m wondering if anyone has advice or a spell that can help me communicate with someone while dreaming

there was a book by Carlos Castaneda, ( controversial author, but interesting none-the-less) About dreaming, and partner dreaming, called The Art of Dreaming, I haven't read the whole thing, but it is the only one I can think of right now. Maybe someone else knows of another one.
