What is the term for awareness of or inclusion of real sounds within a dream?
I think I found a good expression : "sensory incorporation in dreams"

It doesn't seem reflected in a Google Scholar search however, and I don't find a consistent terminology in the papers that do seem to be about the subject. That article can be a good starting point though.

EDIT: other good one: "influence of external stimuli on dreams".
