I had some weird experiences after smoking weed in high school, probably 15 or 16, where repeating patterns I observed while moving would sort of make my vision glitch so that they seemed to be still. It was like if you watch a car in a movie/commercial the tires will appear to be moving backwards or standing still as it’s driving. This happened while I was mowing the lawn with the blades of grass, waking down the hallway of my school with the lockers, and once while I was driving at night with the lines of the road, which kind of freaked me out since I still felt myself moving but my vision made it feel like I wasn’t. I feel that I had seen this happen when I was high and it had triggered this pattern recognition in my sober state as well. However I have never had these kind of visual phenomena happen with weed I have purchased after legalization. I’m not sure if I got something laced or could just handle smoking a lot more weed back then. I had also taken some dissociatives and psychedelics around then as well, so maybe some effect enhanced by them. I did try mushrooms when I had just turned 16 and it really brought a storm of existential questions to the forefront of my mind that were very difficult to sift through with everything I had going on as a teenager. I developed a somewhat unfounded fear of tripping randomly and losing control of my ability to distinguish reality that greatly frightened me. At times I would be susceptible to this thinking, having read about HPPD, and any visual disturbance might lead me to feel tremendous anxiety again that I might be tripping or worse going crazy. One notable occasion I was driving at night and noticed halos around every light. I thought I must be going mad, but nope, it turned out I just needed glasses. Not to minimize the anxiety I felt at the time, but reading too much into some of these things can really make it worse. I never randomly started tripping at any time and my grasp on reality was only made worse by the anxiety at the thought of it potentially happening. Many years since then and feeling I have a much firmer grasp on reality, I just think “my eyes must be playing tricks on me” and bring it up with my optometrist if I see anything weird. However, I do feel for the author having recently gone through a lot of health anxiety after the sudden death of my cat. I did get to the point where I couldn’t drive across town and a sip of caffeine would send me spinning. I guess a lot of things in life can affect you this way if you’re not ready for them is all I’m trying to say, especially if you’re already anxiety prone. Be careful with psychedelics if you have anxiety!
