There are people who have no REM sleep at all and they are just fine. Another interesting is an example with bipolar patients who got put on Lithium. For some patients Lithium impacts REM sleep in a way that it completely disappears but they are just fine.
The deep sleep phases are way more important than REM sleep. You can have REM sleep as much as you want. Without any deep sleep phases it means nothing.
Some patients with PTSD even try to suppress their REM sleep as much as possible to avoid nightmares. When they are successful, they generally report a much better sleep quality.
So more REM sleep doesn't automatically mean that you experience a better sleep quality or will feel more rested.
