In Goethe's "The Elective Affinities," at times in the half darkness Ottilie saw the figure of Edward in a dimly-lit spot. Compare also Cardanus, "imagines videbam ab imo lecti, quasi e parvulis annulis arcisque constantes, arborum, belluarum, hominum, oppidorum, instructarum acierum, bellicorum et musicorum instrumentorum aliorumque huius generis adscendentes, vicissimque descendentes, aliis atque aliis succedentibus" (Hieronymus Cardanus, "De subtilitate rerum").

[48] Hecker says of the same condition, "There is a simple elemental vision, even without sense presentation, through over-excitation of mental activity, not leading to phantastic imagery, that is the vision of light free from form, a manifestation of the visual organs stimulated from within" ("Ueber Visionen," Berlin, 1848).
