People with bpd often experience what is called “psychosis”, which is defined as an impaired reality and chaotic thinking. Psychosis is caused by stress and can last for a few days at a time. When people with bpd are in a state of psychosis they are unable to seperate reality from their inner mental state and can confuse the external from their emotions, thoughts, and fears. It is common for individuals to take something of the past and change it to fit their own reality and viewpoint of the situation.
