It seems similar to what we experience , right now I am waking up shaking like I have a cold again and everything hurts . Its as you said not always definite nightmares but sometimes really blurry things that are triggering . I sometimes wake with the fear to find out more about what happened after such dreams , and its equally stressful for me to only know more awful things happend but not knowing them , and the fear of finding out , its like being stuck in a limbo thats tearing me apartAbout multiple dreams , sometimes the nightmare dreams continue or its about something very similar and sometimes its like having had 2 dreams , remembering both and stuffs but like , not two dreams like waking up and having had another dream but like just waking up and suddenly remember two dreams idk if they happen at the same time or not
