An expression used by Spiritualists indicating the experience of having non-physical sources create images within a person's mind. Even assuming that the images are accurate, they may be of past, present or future, represent something nearby or distant, or may simply be something in the mind that the non-physical source, such as a spirit, wants to convey. Besides numerous potential meanings, the individual who has the vision may also have personal desires, beliefs, interests, etc., that result in a highly personal or subjective interpretation of the images. Although they are clairvoyant in nature, because of the numerous ways they can be interpreted, they may be extremely challenging to someone just developing their clairvoyance or who has never had a clairvoyant experience and not yet developed objectivity in interpreting the image(s).
