Who am I?

I realized today
I was just a guy
Walking in mountain suburbs
In a black t shirt
And blue jeans

A purpose to this life
I have not yet found it
It seems

Is life real
Or am I just
Living in a dream?

I came across a black dog
By the yard fence

I came to close to pet it
But thought again
And made the right decision
By not sticking my hand in

Good bye doggie
I think I said in my head

And tonight I am thankful
To sleep in my warm bed
