[znmcspyy] Dreams as cardiovascular exercise

When you have an intense dream, heart rate and breathing increase.  Does this count as cardiovascular exercise?

If so, perhaps dreams, even sleeping, are a way for the body to be able to do some exercise, in preparation for cardiovascular capability possibly becoming needed in the real world, e.g., fight or flight, when regular life doesn't regularly call for or is preventing physical exercise.

This hypothesis could be tested: do intense dreams increase when deprived of exercise?

Someone else (as dark humor): do panic attacks count as cardio?
