I think it’s a fair assumption that you cant trust memories of dreams. Heck, you can’t even trust memories of eyewitnesses very much. We are all doing a -lot- of active inference and post hoc reconstruction all the time. We just don’t notice the gaps because 1. We are good at it and are often right and 2. People rarely call you out on mistakes even if they’re obvious, because it’s impolite or they are not sure either.

True. To be honest this is just based on having spent a lot of time half-asleep (for science), and trying to remember what's going on, and imagining that I'm better at it than you. I may be dead wrong. I get the impression of a process of rationalization at the point of waking up (which I like to do slowly). But then, you got an equally persuasive impression of a vivid detailed dream, probably, so at this point it's just one impression against another, that's qualia for you.
