Can someone teach me to dream?

I thought every human on Earth had this capacity,

It's supposed to come very easy,

Everyone is supposed to be able to dream,

And have real goals it seems.

But for a reason,

I don't have any real goals,

I have no plan of action,

I just follow the other's controls.

It seems like I don't have my own brain,

But somehow my own brain I don't seem to own,

Or that it has been drained,

Why can't I think alone?

I don't have plans for the future,

I don't know what I want to become,

Actor?

Baker?

Boxer?

Or even beggar?

I convinced myself that I live day by day,

But I know inside it's a lie,

Because on my 18th birthday,

I still won't even know what I'll do with my life.

Everyone around me,

They already know what they like,

They know what they want to be,

What makes them happy.

Can someone teach me to dream?

I would really like to have my own goals,

My own brain,

Or else I am going to become insane.
