I noticed that a good portion of your dreams end with choking. Do you have sleep paralysis? Many of my nightmares ended with me drowning, being crushed/smothered or being strangled. Then I "wake up" to complete darkness, unable to breath, see, or move for what seems like forever before snapping awake in the morning. The ending of your dreams reminded me of how many of my dreams/nightmares use to end before I was prescribed prazosin. This med really help to manage my sleep paralysis and a certain recurring nightmare that would scare me so bad that I would sometimes wet the bed. Thanks to the prazosin, the last time I had this nightmare was two years ago.

All of your nightmares have to do with failing someone or being helpless. All of my recurring nightmares have to do with me disappointing someone (usually my family) or me being brutally victimized all over again. Do you see a therapist? You need to talk to someone especially trained for that. Maybe you need meds, as well. IDK but personally prazosin is the best thing I was given for my recurring PTSD related nightmares.
