According to St Nikita Stithatos, the differences between dreams, revelations and visions can be discerned as follows:
- Dreams are “images that do not remain unchanged in the imaginative faculty of the nous,” the heart of the soul. Dreams “present a confused picture with constantly altering scenes and forms . . . [they are seen by] materialistic and sensually-minded people;”
- Revelations are theorias of the mysteries of God, “granted to the purified and illumined soul in a way that transcends normal sense perception . . . [they are granted to those] who are activated by the Holy Spirit, and whose soul is united to God through theology” (theoria). Revelations are associated with inner purity;
- Visions are constant and unchanging. They also “remain imprinted on the nous unforgettably for many years . . . [visions are present in] those well advanced on the spiritual path, who have cleansed the soul’s organs of perception.”
