DXM can change our senses?

“I was born with a congenital cataract in my left eye. Due to concerns about my young age, surgery was delayed, and I developed monocular vision, relying solely on my right eye. At 23, the cataract was removed, but my left eye’s vision remained limited to light and dark perception. Later, as a pharmacist, I experimented with high doses of dextromethorphan (DXM). I observed that DXM appeared to affect my pupil size and, remarkably, allowed me to perceive colors and close-range objects with my left eye, albeit temporarily. Additionally, DXM significantly altered my sensory perceptions, increasing my cold tolerance and diminishing my sensitivity to personal hygiene. Given these profound effects on sensory processing, I wonder if DXM or similar substances could potentially offer therapeutic benefits for individuals with autism spectrum disorder, which is often characterized by sensory sensitivities and perceptual differences.”
