Minor Project - Boy vs Bed Idea

At the moment I am drawn to the idea of creating an animation that is about a boy who is scared to sleep. His fear will manifest in his bed that comes to life as a monster, the boy will have to fight off his bed even though in reality he needs to sleep. After talking with Phil about the idea he suggested I look at 'The Melancholy Death Of Oyster Boy' by Tim Burton, we discussed how the animation could have an accompanying poem. 

I've started to jot down some verses for a potential poem, it's very rough at the moment so it definitely needs some refining. I am also at the moment unsure if it should have a happy ending or perhaps an ending in which the morning comes and nothings happened (the boy is just tired). All of that will need to be figured out, but here is what I've written so far:

There once was a boy who was scared of his bed

Before he would sleep bad thoughts filled his head

Would he survive a whole night that was dark?

Or would he be inhaled by his bed like a shark.

Would he be safe wrapped up in his cover?

In the dark he may be hard to recover

Can he hear noises from behind the door?

The sound of a monster who let out a roar

Could his room shrink in the blink of an eye?

This poor boy just feared he would die

If he fell asleep would his life fade away?

All of these fears the boy needs to slay

Any feedback or advice would be greatly appreciated!
