I Sensed a Presence

I sensed a presence, over by the stairs,
Next to the red armchair.
Nothing was stirring, not even a mouse,
That night as I was prowling about the house.
When I heard something thump.
And I whipped around with a jump.
Do I sense a being? An apparition?
Why, I thought those were simply non-fiction!
I crept along,
My confidence long gone.
When again I heard a thump.
And once more I looked with a jump.
To see my simple black cat,
Jump onto the chair like that.
He landed with a thump.
And I felt like a chump.
