You will see ever-changing phospenes. Even children can notice this phenomenon very clearly. This rose will look like a faint transparent object in darkness. At that time you will start to notice that darkness becomes three-dimensional instead of flat. When you learn to focus your attention onto darkness you will reach a pre-hallucinogenic step which is the step of reiterated images .
Reiteration seems to always precede the generation of complex images by the brain.
Reiterations express something fundamental about the workings of the CNS and how it works in order to synthesise complex three-dimensional images. My examination of this phenomenon leads me to think that the famous Dutch artist Escher had pre-hallucinations of this sort and that he drew them as art. Reiterated images are always in rotation This can be observed either with this method or under the influence of disattenuating molecules, such as psilocine, LSD, etc. The rotation of the reiterated image is slow , perhaps about 5 seconds per gyration . While rotating , these images can change into other reiterated rotating images .
