Can having PTSD and depression cause morbid thoughts/curiosity?

although i am not an expert i do have a job and many certifications in the medical field. most everyone has thoughts of how people die what happens after death embalming and all that like you are describing. i know when i went with my nursing class to a lab filled with bodies donated for science i spent weeks thinking about people and imagining myself dead. and now i am in the fire department i find my self going ot of my way to look up deadly accidents just to see the damage. but your visions and thoughts of killing yourself or finding yourself dead is not normal and my be your body's way of trying to tell you of an underlying problem. defiantly PT-SD can cause these thoughts and it is important to talk to your therapist about these thoughts. i do not know you very well but from reading this question you do not sound suicidal or of being a threat to others or yourself so i would not admit you but as i said i do not you know as you therapist might. the thing is is these harmless thought might trigger a different disorder and take over your life so i can not stress enough how important it is to talk to your therapist about these thoughts.
