I tried searching for this subject and there are threads about using a lucid dream to relive an old memory (which may or my not be subject to false memory formation), but that isn't the entire idea I have here.

What I am getting at is to do something different during a certain phase while reliving the memory. Any result after that is not a memory and is whatever my subconscious mind creates out of it as I react, but I want the experience of having this moment play out differently for personal satisfaction or closure if I have to find some word for my goal.

I do not know how doable this is since I am beyond lucky if I go lucid even while using many supplement combinations, so I do not know what it is like to relive a memory through lucidity yet alone breaking off course.
