What should be called a Perfect sleep

I don't have a notion what a perfect sleep is and i think i haven't been sleeping a perfect one ever since i became aware of my dreams. To sleep at least 8 hours without remembering my dream would be a perfect sleep for me. Drinking warm milk at night, having a clean comfortable bed, a soft pillow and warm nice room would lull me to sleep!

A perfect sleep to me would be around 12 straight, Then I felt so comfortable the moment i woke up, My eyes and my body wont feel any pain because usually there were times I slept in uncomfortable positions. I also dont want to have cramps, sleep apnea or any sleep disturbance. If I have a wonderful dream that i can remember the moment I wake up, its a good sleep too. I want to wake up feeling happy, rested and energized.
