All I remembered for yesterday was I literally open my mouth and breathe manually.
A total Nose-block.

And it is like choosing survival or sleep. (Both are VERY important)
No use of choosing sleep when u cant breathe, right? (Not that I can choose)
So mind-awaking (with eye closed) the whole night. Desperately need to sit up and breathe (unblock one nose nostril )


Conclusion: I am a ZOMBIE today.
