One that is certainly worth a read is The psychedelic nature of Islamic art and architecture where he takes a look at the psychedlic kaleidoscopic patterns which are found in Islamic art and architecture.
A common DMT experience is finding oneself in a vaulted dome structure. In DMT lexicon, ‘The Chrysthanemum’ is a gigantic, rotating, fractal flower that has a dome-like appearance. Terence McKenna said you could either pass through ‘The Chrysthanemum’ and enter hyperspace or stay put (if you didn’t take enough DMT). However, many DMT users also say the vaulted dome space is a revered destination and it’s where you go during a ‘breakthrough’ dose of DMT. McKenna himself called this post-Chrysthanemum place “the dome”, adding:
It’s softly lit, indirectly lit, and the walls—if such they be—are crawling with geometric hallucinations: very brightly colored, very iridescent with deep sheens and very high reflective surfaces. Everything is machine-like and polished and throbbing with energy.
It has been suggested that geometric hallucinations are a projection of the structure of our brain, stimulated in a variety of ways (e.g. drugs, conditions like migraine and epilepsy, near-death experiences, sensory deprivation, fasting, hypnagogia, and so on).
I do agree that Islamic art and architecture are some of the finest traditional examples of this kind of aesthetic expression. Their striking similarty and resemblance to psychedelic experiences certainly suggests that they may have been inspired by entheogenics.
