Am I in reality?

I look around
 At the town
I hear the sounds
I do not frown
I am in a book
That feels real
And I am hooked
I feel in a trance
As I take a glance
I feel I am the storyteller
And it is going to be a bestseller
I hear no one around me
I have drifted to another planet
I am free
I am me
Is this reality?
