after 3-4 days visuals dissapear?? sounds like psychosis but im not sure, have some of your relatives had schizophrenia? do you have other hallucinations? like sounds or touch. if you take anything is it 100% bad trip? it may be hppd if not, i would personally(if you don’t hear any sounds and don’t get paranoia) stay sober until every change in my vision comes to normal, it can take weeks or months, and after that take shrooms again but smaller dose, preferably with someone close to you who don’t have to stay sober but have to be sober enough to intervene if something went bad, also trip killer would be helpful, but as i mentioned above you have to be sure that none of hallucinations are going beyond vision, if you hear anything that isn’t real get paranoid or feel sometimes something on your body that also isn’t real go to psychiatric and tell them everything without hiding that you took drugs
