The significant place given to such descriptive and detailed visions among the Roman Catholic "mystics" is a peculiar feature of post-Schism Roman Catholic "spirituality" and is not compatible with the spiritual sobriety and warnings against such phenomena that are characteristic of the pre-Schism saints and Fathers such as the Desert Fathers, St. Anthony the Great, the writers of the Philokalia, etc. The Orthodox approach to such phenomena is in agreement with the approach of the early ascetics and hesychasts, and can be described as follows:St. Neilos of Sinai
"Do not desire to physically see the Angels or Powers, or Christ, that you may not lose your mind from accepting a wolf instead of a shepherd, and worshipping our adversaries, the demons."St.Diadochos of Photiki
(5th century) on Spiritual Knowledge, p. 264, Philokalia Vol 1.
“We have now explained the distinction between good and bad dreams, as we ourselves heard it from those with experience. In our quest for purity, however, the safest rule is never to trust in anything that appears to us in our dreams. For dreams are generally nothing more than images reflecting our wandering thoughts, or else they are the mockery of demons. And if ever God in His goodness were to send some vision and we were to refuse it, our beloved Lord Jesus would not be angry with us, for He would know that we were acting in this way because of the tricks of the demons. Although the distinction between types of established above is precise, it sometimes happens that when the soul has been sullied by an unperceived beguilement – something from which no one, it seems to me, is exempt – it loses its sense of accurate discrimination and mistakes bad dreams for good.”St. Symeon the New Theologian
(ninth century) On Three Kinds of Prayer
"[To] imagine heavenly blessings, the ranks of angels, or habitations of the saints…is a sign of prelest (delusion)."
"They are deluded who are on that path, who see light with their physical eyes, smell fragrances with their sense of smell, hear voices with their ears, and suchlike."
