A person having a bad trip might try to harm themselves or others around them. They may experience suicidal ideation, or make full-blown suicide attempts. Because of the magnification of emotions they induce, many psychedelics could possibly cause thoughts of death and intensely adverse reactions in some users. Users can believe that their death is imminent or that the very universe itself is collapsing. Rapid "aging" of other people may be observed by the user, perpetuating the aforementioned fears to an even greater degree.
