She seldom turns up alone in a dream, arriving instead with a whole house, a chair and the smell of a kitchen attached to her.
A grandmother rarely appears by herself. She arrives with a house attached, and sleepers report the room, the cooking, a particular chair and the texture of her hands far more vividly than anything she said. The traditional reading follows that setting: she is taken to stand for continuity, for the keeping of a household and its stories, and for care that turns up without being requested.
Older books tie this figure to the home because that is how the households they were written in happened to be arranged, not because of anything essential about grandmothers. It is worth reading as history rather than as a rule. Many sleepers meet a grandmother who ran a business, farmed, emigrated alone or held a family together through a war, and the dream figure carries that life rather than a generic apron.
A great many people report being told something. A word of caution, an instruction, a question they cannot answer. Folk tradition treats such speech as guidance handed down the generations, while readers of a more modern cast treat it as the sleeper speaking in a voice they are prepared to listen to. Either way the advice deserves thinking about on its own merits, which is a good deal safer than obeying it.
The woman in your dream is not the archetype in the book. Someone raised by a grandmother has a mother in that chair. Someone whose grandmother was cold, or who never met her at all, has an absence sitting there instead, and an absence reads very differently. Take your own history first and the general meanings a distant second.
