Just my imagination?

When I write my poetry
I don’t always think of me
So often things I jot down
Can be about anyone you see

So if I say I’m mad 
Or something negative instead
It isn’t me I’m on about
Its just someone in my head

Please don’t you worry
Theres no need to feel alarm
Its just my imagination
It doesn’t do me any harm

Poetry is rewarding
I find myself in others shoes
Its absolutely fun
Using characters I choose

I wander off if I’m alone
It stops me from being bored
& If I end up with a good one
Then I know my brain has scored ??
