• The client is no longer able to regulate levels of serotonin

• The body secretes too much melatonin, which leads to an increase in nightmares

• The client may have a hyperactive amygdala that leads to an increase in feelings of fear

• The client’s pituitary gland works in overdrive and consistently causes flashbacks
