Some good responses from both of you
Just one thing to watch out for. If you feel tired in the morning it might simply be sleep inertia (ie. you woke up in deep sleep, which is tough to shrug off entirely)
This doesn't necessarily mean you didn't get enough sleep though, so keep it in mind

I also feel that unless you feel yourself getting more and more tired as the days wear on, I really wouldn't worry about it.
People have a lot more dreams than they realise - they simply don't remember them all
