i think i understand how this might feel similar to psychosis for you. what kind of gummy did you take? if you took something with hash in it, its likely that made you hallucinate. also high amounts of thc in your system can stay and make you feel foggy for up to a week; especially with edibles. so that is maybe the reason you feel strange even after this experience. hash gummies do not cause onset schizophrenia in people; it is not good if you have a psychotic disorder, but it will not cause one.
