Quantum Poem?

Someone was talking to me today about some computer game or other that I'm not familiar with, but it somehow led to a discussion about something called 'quantum poetry' which apparently features in some little scene in the game he was discussing. The idea is that you have to write a 4-line poem, with two rhyming couplets, but it has to make sense no matter which order you read the lines in!
Well, Rory does love a writing challenge, and obviously I have nothing better to do on a Friday afternoon at work, so I gave it a go...
And this is what I came up with: (I won't give you all 24 versions, but I can assure you they all work!) I have to say I am rather proud of it:

 

A lakeside cabin dark and warm

A creeping fear, a nagging doubt

Shadows casting eerie form

Beating hearts and muffled shout
