Thought Watching

I hung upside down for long enough
That my eyes flipped back,
I saw the stuff –
The whizzing, whirring thoughts that bubble up.
The busy minded madness
That we all know and love,
Fizzing up in pops and puffs
(Plus I think I saw a bug).
Got a few puzzlers, loads of fluff,
But to find a few that are up to snuff
You have to go on quite a hunt.
Thoughts are easy, thinking’s tough.

Now how do I flip my eyes back front?
