As Wilbur remarks, the fluid shifting of the figures suggests the behavior of
hypnagogic images; but the agitation of the draperies would also produce a perpetual ambiguity of architectural form, and the effect would resemble that which Pevsner ascribes to the interior of San Vitale in Ravenna; "a sensation of uncertainty [and] of a dreamlike floating." (Wilbur 1967: 112)
The declared aim of the artist is to give dreams, visions, and
hypnagogic images the force of concrete reality.
There are abundant examples of phenomena that appear to utilise such a confusion: spontaneous cases, which often involve "realistic dreams," lucid dreams, false awakenings,
hypnagogic images, waking imagery, and sleep paralysis; and states in which reality and imagination are often confused.
