I have had a pretty mild-average case of HPPD for the past few months. Caused by LSD, Mushroom use and exacerbated by constant use of cannabis.
When i move my head slightly to the left while looking at a textured surface such as asphalt, to the right of the center of my vision, it's as if all the edges of the rocks in the asphalt swirl around this one point. If i move my head to the right, the same thing happens but to the left of the center of my vision. If i don't move my head at all, i notice textural anomalies kind of like an LSD trip, but without the normal structure a psychedelic visual has. Does anyone know what this could be? I have a predisposition to schizophrenia in my family, I've dropped a LOT of acid and mushrooms in the past year, and I'm rather worried it's something schizophrenic in nature. I am completely here in the head, mind you. Aside from the normal far out theories about reality that psychonauts have, I am normal. I do not consider myself delusional, and any theories i have from these experiences are valid and make sense to completely sober-minded people. I'm just wondering if i'm in the early onset of schizophrenia, or if i have HPPD. I have many other hppd symptoms, such as colors shifting, halos around lights, trails behind moving objects. I'm wondering if the symptom i've described above is what people would consider patterns in a textured surface. I've also wondered if it is palinopsia. Anyone want to shed some light on this?
