Dream!

I have not been getting dreams while I sleep in the past few weeks.

As a habit, I played music before I sleep. I don't play lullaby, but chinese pop, especially singers like Jay, Jolin, FIR, Cyndi, J-pop, Utada Hikaru, Ayumi, etc .
I noticed that as soon as my hearing senses went off, I'm as dead as a log.
The next moment when I opened my eyes, it is morning .

What I feel is that I might be missing something- my dream phase!

This kept me wondering if dreamless-sleep is good or bad, because I wouldn't like to have a nightmare or something popping into my head when I was asleep.

Maybe I have inbuilt sleeping-pill ability?
