I've semi-recently been experiencing an increase in sad dreams, without a comparative increase in stress in waking hours. Before, I occasionally had some sad or bad dreams - not enough to really note - but now it seems I can't have more than three consecutive sleeping periods without one of them ending in a sad dream.

I'm wondering if that's significant or not.

Note that I have Complex PTSD and therefore am always under a high level of stress - but there has not been any changes to that stress level in memory.
