Nightmare or something more?

It's 11 o'clock and I am still in the office. It's Saturday by the way.
I am exhusted. Numb at the same time.

I am dreaming about a house, that it's windows opens towards the ocean.
I even can not listen to music.
My ears can't distinguish notes.

A bit before, I listened to Valerie by Amy Winehouse.
And that was it.

I am surrounded by something which is numb itself.

Sometimes I forget why I am working.
