Is it normal that my mouth feels fresher when i don't brush my teeth

When I don't brush my teeth in the morning before I eat...after I eat, my mouth doesn't feel dirty. But when I brush my teeth in the morning, my mouth feels dirty and my breath doesn't feel as fresh. I have gone hours without brushing my teeth and my mouth feels better than it does when I do brush. I have good oral hygiene; I brush morning and night and sometimes during the day, I floss and I use mouthwash. But sometimes I skip. I wonder if anyone else feels like this? Of course I brush eventually because plaque builds up and it looks nasty but I notice that after I brush, I get bad breath. Is this normal?
