Why do I keep dreaming it is Friday?

I was really tired today. Haven't had enough sleep the past day so needless to say, I knocked out around 9 plus.

But I had this reoccurring dream that it is Friday and my mind kept trying to wake up but somehow my body just couldn't bother at all. But still, my mind kept insisting to wake up.

Somehow my body prevailed and I woke up just in time for breakfast and now I feel so refreshed.


Moral of the story?

Listen to your body.
