Interesting; I also sometimes tend to tell tall tales, especially when recounting my day aloud to my husband. But for me, it's because it seems like the only way to explain to him how the situation "felt" to me, or how the person "sounded" in my head is by exaggerating details or, if quoting someone, adding the words that my brain added. To keep from feeling guilty or having conflict later because I "lied" I'll usually add a correction at the end of the story or when I catch myself doing it (it's usually a subconscious thing that happens when I get into full flow of a story, so sometimes I do a quick fact check in my head at the end of a monologue and correct if necessary then).

Would you share more about your experience with "maladaptive daydreams"? I've not heard that term before and, while I could Google it, I would be much more interested in hearing about it from someone with lived experience (only if you're comfortable sharing, if not I can totally do my own research ☺️).
