How do hallucinations appear through reversing goggles?
Karl Jaspers describes clinical reports in which patients hallucinatory perception was changed in accordance with the optical distortion. For example, a prism would double the images of devils, binoculars enlarge or decrease the image, colored glasses make it colored, etc. He refers "Seppilli, Contributo allo studio delie allucinazioni unilaterali. Riv. sper. di fren. 16, 82. 1890" and "Pick. Beitrage zur Lehre von den Halluzinationen. N. C. 11. 329. 1892" Now, the question is, has anyone done a study on that in the 20th century.
