The Peculiar Place (part 1 The Poem of Beginnings)

I walked outside to get some air

But was surprised by what I didn't see there.

Nowhere was it to be found

It was gone without a sound.

My eyes bore down at where it should have sat

And saw something else very wide and flat.

What to make of it, I could not decide

So I got on my hands and knees near where it lied.

I pressed my face so close ere I was upon it
Pondering why it was here and why my thing was not.

Suddenly it opened up and in surprise I slid  forward falling in

Tumbling deeper and deeper in an uncontrollable spin!

I hit the ground with grunt and pulled myself to my feet

My entrance closed,worry descended on me, can you feel the heat?
