My grandparents (and therefore I assume their older generations who taught it to them) said "Friday night's dream, on a Saturday told, will always come true, be it ever so old"

I also know the not-before-noon superstition was blended into this, so no dream content from friday night can be shared on a saturday morning. You could risk it in the afternoon I guess. But it's not every day this applies in my inherited belief framework, which happily frees up the rest of the week for sharing dream content right away.
