Really Bad Poetry Time!

I couldn't sleep last night and this is what my brain had to get out before it would let me rest:

I hear it in my head
Words of a snake slithering
Dragonfly paths and bird wings
Words that aren't there
That don't exist, aren't real
They fill my head
Try to escape
I ramble endlessly
But it does little
To empty my mind
I can't find peace.

I don't actually understand it at all. I'm used to not liking my stuff, but this is the first time I've not been able to figure it out.
