I do have similar experience. Only one big difference that I'll quote below. I use LDs to understand all that I am more and watch all the images that my unconscious show me in the manifestation of the dream.

I would describe this as a sense of lucidity that rapidly emerges as a response to negative emotions
.

I intervene in this kind of dream only if I have a lucid nightmare ( which I learned recently. by myself, how to defeat it ) but I dont become lucid because of a nightmare, I am lucid and have a nightmare. so it's not a response to negative emotions ( for me ).

After I wake up I analyze the dream.
