I've been interested in the visual patterns that appear "in" one's eyes under the influence of certain substances ever since I had the first such
experience. (It was a perfectly OTC substance, not '___' or anything like that.)
I have visited many websites that propose explanations for it (including Erowid and
which also links them to migraines - which in my case is BS, I've
never had a migraine of any description in my life).
Some, as the article mentioned above (see the URL), explain them in mathematical terms, which makes sense , of course - up to a point.
But the purely physical/neural explanation proposed in the article does not account for the incredibly detailed Islamic floral patterns
that usually appear in front of my eyes. (How do I know they are "Islamic"? Because I am familiar with art history.)
Now, such patterns do not exist in my actual physical environment, nor do I spend much time contemplating them in books (the last time I studied them
was a few years ago), or even thinking about them. And I'd like to stress, once again, that they are FLORAL - not geometric - patterns: incredibly
detailed (and gorgeous) stylised floral patterns repeated many times (the effect is very similar to ceramic tiles).
Here is another article
, but I'd prefer informed personal thoughts and comments,
if there are any.
And another question: could - physically, I mean - the "mesh" or "net" patterns (I also saw those on several occasions) be caused by the net-like
structure of the retina itself?
It doesn't seem very likely - the retina observing itself? - but I'd like to know for sure.
