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.
