you may be tuning in to subtle vibrations around you, or quantum positioning patterns...there really is an energetic pattern in which things are connected. matter is and is not in different places based on universal harmonic patterns. or at least that's my understanding and take on relating quantum virtual particle patterning with larger level experience...i guess you can take the same idea onto the dimension of dark matter..being matter which is solid beyond all solidity we know, and the web where dark matter lies, is where what we view as solid is placed...ie the patters of galaxies and clusters. i guess i can say things wind up where higher dimensional (or higher energy) stature allows (or grants)...
lol, i'm no physics expert, but i have read things through the years which help me to explain the way i see the world.
when i'm in an open perceptual state, be it through psychedelic trance, or simple meditations i can see the mandalic patterns which connect all things. and like you said, if i tune into the objects for their material value, i instead notice the physical forms and am not 'tuning in' to the energy patterns.
the other geometic visualization i notice is to me a visual representation of the intellectual processes of the subconscious mind...the dance of the patterns evolving is correlative, for myself, to the expansion of my neuropatterns and the growth of my understanding. and no better picture can be painted to represent this undulating growth process than an ever-evolving mandala...as we grow our understanding evolves into furtherly intricate and furthely awe-inspiring forms. for me these forms can be 'formless' if i go about my life and don't meditate, however when i relax my mind and focus i can see my body working...sometimes this presents itself as visualization of bodily process, sometimes it's a visual representation of cognitive process...kind of like a daydream without symbols...just raw geometic matrix code :D
from my own experience i believe that there is much much much much more information and stimulus going into our being than is represented in our 'mundane daily view of the world'. i think psychedelics can open people up to processing different stimulus, or also likely they can open people up to processing More stimulus in a given amount of time...i think distraction or 'disorder' comes from this 'tuning in' only if the person is unable to logically process and assimilate the stimulus into something usable.
for myself, there have been times through the years that the sensitivity i have to people emotions and the amount of stimulus that i process in a given moment has been burdensome and overwhelming...but overall i am grateful for the elaboracy which i see even in a wall...i find lesson in such....even in mundane occurance the universe's dance is no less intricate/powerful.
practice meditation if you feel overwhelmed...learn to access your own 'true view' of reality without psychedelics...that way you can accurately decipher what is enhanced sensory experience or simply daydreaming delusions...for the psychedelic experience is the viewing of one's own energy as well as the enrgies around ones self. when you have delusions within yourself, you see delusions....when you are absolutely centered and clear there is the white light of true experience, which goes beyond mind, beyond emotion and encompasses the entire self.

a lot of words i know...sorry if i'm rambling, or if it's too hocus pocusey...it's intense and generall wordy to try and linguistically bridge the gap between psychological perceptual experience and existential reality experience....
hope this gives a little reassurance in the least...if i could only show you what i see....lol, much more than fractals...shamanic trance is something which i feel isn't mean to be explained here now. just know that there's very powerful things to view around one's self which are as solid, and even more solid (from my own subjective experience of touching dimensions :D) than what we tend to think is 'all there is'
best of journies friend, if you are interested in more information about what i've learned regarding energy patterns and the like pm me... :D
