Can ocd make you have a false memory under stress of doing something u don't wanna do and think is gross, but for a second u think u saw urself do it?

Yes: People suffering from OCD may have intrusive, recurrent thoughts that are disturbing. They may involve sex, aggression, contamination or blasphemy. Many pts have severe guilt & shame about obsessions. Fear of loss of control causes increased anxiety. Repressed anger may be a cause, but confrontation by gradual exposure to thoughts may decrease the severity of anxiety w/o fear of acting out on them
