i've disappeared

I stare at the teacher but,
I hear nothing as,
I turn my music louder.
The class moves around me and,
The sunlight shines in my eyes when,
The time slowly passes.
I stare at the teacher as,
I watch his movements and,
I snap.
The class stares as,
The contents spill on the floor but,
The world keeps going.

I've been lost.
I've been gone.
I've disappered..
