My last one i had paranoid delusions, paranoia can cause you to feel threatened or in danger, and illicit a dangerous response to the perceived threat.. they make people dangerous, hence (and rightfully so) some of the stigma with mental illness. I slashed my sisters tires because i thought she was out to destroy my life... paranoid delauions can become dangerous, and ive now had them, and i scare myself sometimes because i just dont know what I'll do next, and i cant always trust my intuition...
