No. What you're describing is basically the equivalent of sleeping 7-8 (or whatever you consider a normal duration) hours and having a normal day. If you stay up 9 hours, or even more than one or less, you basically break the cycle. As far as know, you can only really re-enter REM if you stay awake a short while after waking up in the middle of an REM period, and fall back asleep. If I'm not mistakenm this is basically why WILD works well. You're staying conscious while going into REM, where you have the most vivid dreams. But if you stay up too long or get very awake, it's over.

EDIT: Except if you're talking about naps, where you usually go into REM easier/quicker.
