Howcome nobody talks about the nightmares?

I'm 6 years post-stroke and regularly have nightmares featuring apocalyptic themes and vividly terrifying scenarios where everyone is trying to kill me. I have always been prone to nightmares, but the subject matter of my nightmares these days is particularly jarring and seems to have only gotten worse with time.

I know I have PTSD. I already had PTSD, and now I have it from multiple sources. It doesn't help that I got cancer a few years back (and have several chronic health conditions) and live with the distinct fear that my body IS trying to kill me.

I feel like this is an aspect of recovery that I haven't seen discussed, perhaps because there's not much to be done about it. I live a decent life, I have recovered many aspects of my physical and mental health, and I'm doing the best I can to move forward. But somewhere in my subconscious mind, I am terrified. I know it could happen again at any moment. I know it could happen to anyone I love. I'm afraid of losing my mind, of losing someone close to me, and I'm afraid I'll never be able to move past that fear.

I don't need advise. I guess I just want people to know that they're not alone, because I know I can't be alone in this. Everyone knows me as a strong person who has gotten through some really tough shit with a smile on her face. It's messy on the inside. I think that's okay. I just wish it didn't have to be this way.
