Overactive Imagination

Laying in my cozy bed And drifting off to dreams, A sudden panic fills my head: What if this isn't as it seems? What if while I'm tucked in, Slipping into sleep, Giant monsters and their kin Through the darkness creep? I draw my hand back to me, deep into my sheet, Scared that if I leave it free Something monstrous it'll meet! It's not like this is new to me When I'm alone in my abode. Frightsome beasts I fear I'll see- Is there one in the commode? Sure, to you it's just a toilet Standing stock-still in the loo. But of my mind, when I fear and fret, You haven't got a clue. Yes, I know it's just machinery, But maybe when I flush Horrors will purvey the scenery, Responding in a rush. Eek! Stop talking! Wait, wait, wait! What's that above our heads? A rusty, musty AC grate, Is that what you just said? I know it's dust, I know it's shadow Behind the grate's steel bars, But looking up from down below I see a face pockmarked with scars. As I brush my pearly whites at night I risk a glance up high, And then I nearly die of fright And soon begin to cry. I see the face, still staring down, Watching me brush my teeth. Daddy runs in and looks around, So I heave a sigh of relief. He gets his tools, tells me to look, And gently unscrews the grate. I watch, see neither beast, nor crook, Nor any evil trait. After all this time, I've come to see That I don't need to fear. Creatures lurk not in shadows near me, Nor every creak I hear. I've come a long way, and I'll never go back To how I was before, When from every crevice, every crack I feared beasties would pour. What's that? It's time to go to bed? Ok, I guess you're right. But, um, well, before you go... Would you please leave on the light?
