I don’t know if this is useful but when I’ve done soul-travel (for example to effect a healing, and the person has confirmed to me that the healing worked and had lasting effects) then the memory of that soul-travel and the things I did and saw feels like an actual memory of doing something in this world, compared to the relative jumble of a dream. And I will have no memory at all of my body in the ordinary reality, even when loud drumming is playing to support the trance.
Sometimes I’m so engaged that the memory isn’t complete and linear (which is why I record them using a voice recorder) but if I recall a fragment of it, the memory’s as vivid as the first day on a new job or anything else that sticks in your mind.
Daydreams, no matter how much fun, are usually more hazy with time, and harder to remember out of sequence - if you asked me what happened just before a real and dramatic event in either real life or soul-travel, I could recall it with relative ease; if you asked me what happened just before something dramatic occurred in a daydream I’d have to backtrack then start re-running it forwards again, because it’s not a real memory, it’s a kind of story that only exists in a linear form.
I hope some of that’s helpful but as with anything about how your mind works, it could be that what applies to me isn’t useful to you.
