The only times that I can remember in my dreams where everything is very normal and my day plays out verymuch like it might in real life is during a false awakening after I try to WILD.
So maybe you are having something similar.
I would suggest doing reality checks in real life everytime one of these everyday life things happens, the things that make your dream seem so normal. And then you may remember to reality check during your seemingly rralistic dream. if any of that made much sense...
