What you describe sounds like strong physiological activation with a muted “trip layer.” That can feel like big pupils, shaking and nausea, yet few visuals. It is not the same as no effect. Some people mainly get bodyload and emotional shifts while the visual component stays light.
Common reasons include recent tolerance or microdosing carryover, meds or supplements that blunt 5‑HT2A signaling (for example SSRIs, antipsychotics, benzodiazepines), individual variability in imagery, and a stressy set and setting that keeps the nervous system in high gear. Purity and dosing are also key. I cannot verify what you took, so assume uncertainty if it was untested.
Practical approach: do not just raise the dose. Space sessions generously, keep stimulants low, and use a calm, dark environment with comfortable body temperature and minimal sensory clutter. Review anything you are taking that could dampen effects, and consider substance testing so you know what is on the tab or in the truffle product.
Reports of strong body effects with few visuals do exist. See this similar case about very high truffle intake with little trip: 90 mg psilocybin from truffles and no effect or trip.
Hope this gives you a clearer way to troubleshoot while staying safe.
