Does the Goddess communicate, and, if so, how?

The same way any other deity would communicate to a person, I imagine. Through signs and omens, through dreams, through feelings, appearing in mediations with messages, speaking to the person... I don't believe that people who claim to communicate with the (pagan) Goddess experience anything different than people who claim to communicate with (the Christian) God, or with the (pagan) God -aside from the gender differences bestowed upon deity by our human minds.
