Psychic visions may occur in dream state, in waking life, or during psychic meditation.
Everyone may experience psychic visions. A psychic vision is an experience so clear and vivid that it often makes more sense than our regular waking lives.
(A psychic vision can also be called an experience of illumination.)
Most often psychic visions are triggered by an emergency, either physical or spiritual in nature. Such emergencies force us to step beyond our boundaries in order to survive.
A psychic does not wait for emergencies to experience psychic visions. The psychic adamantly pursues the clarity than can be experienced in psychic visions and integrates that kind of clarity within oneself.
A master psychic is almost constantly in this state of greater clarity and has so much control over psychic visions that they become to be a continuous second sight.
