Reality? Poem by Edward Grey

As I walk through my day
Taking numerous steps
I think

What is real
What is not
How can you tell

I can easily see
Every thing that is around me
But is it really there

How do I know
This is not a dream
How do I know that I am a living being
How do I know that what I see
Is reality

I see blue
You do too
But how do I know
That the blue we see is the same

I feel like I am on the verge
Of something I cannot see
Like I could take one more step
And walk into a different reality

It might just be
That we are not real
That everything that we can touch and feel
Maybe our souls can see to the other side of reality

When we die
Will we see
The other side of reality
