I guess this sounds quite weird
I have a boy inside my head
I can talk to him, as I feared
And this is what he said;

My name is simply Brian
I am a boy, who knows all things
I help to do these things, like rhyming
And I even move your limbs

Now Brian, I said, to my head
Are you really there?
I know, without you I'd be dead
But I didn't knew you cared

Brian is the cleverest boy I have ever known
He sits just above my eyes and ears
He's always there for me when I'm alone
.There to make the tears

I know he will never leave me
He can't, he is locked in
It wouldn't be right, to call him a brain
Because after all I am insane
