Waking up from REM

Im waking up now alyways at 4 o´clock to write down my dreams, then again at 5, and 6 and I wake up entirly at 7. I go to sleep at 9-10 I heard you can start to get really irratible when awake if you get disturbed constantly from REM.

Is being tired and irratible just a price to pay for dream recall or am I doing it wrong?

Any insight would be great.

Have you noticed it bothering you? I would just trust how you feel. Your body will tell you if something is wrong.

Why do you wake up every hour? Isn't a typical REM cycle about 90 minutes? I would think it better to wake up every 1.5-2 hours or something? Every hour seems a bit excessive.
