Spirit Guide dream meaning is explained below using 2 different sources. Each interpretation is shown with its source.

Interpretation 1 — Theresa Cheung

Spiritualists, shamans and mediums often claim that spirit guides visit them in their dreams. The spirit guides often appear in the forms of animals, but may take on other forms: the form of loved ones already passed on, past teachers or elders, or important figures in the relevant mythology. According to Jungians, archetypal figures, such as the wise old man or the priestess that appear in dreams and offer guidance, are not guides from the spirit world but from the depths of your unconscious. Either way, they perform the same function as spirit guides. So if supernatural or archetypal figures appear in your dreams, are you in need of some sort of guidance? Could you use any of the advice they offer effectively in your waking life?
