Ethereal

 I've never nictate I'm too curious and I move of my own will so don't pretend to see me

I'll conceal from you in cranny of psyche you have no conception nor even idea of

I'm what you mayhaps lost down the back of the sofa I'm tiny and at same time stone-cold 

I shine in the moon's dim light keeping the dark away Yeah That's how it to be called

Step out from darkness Yeah I'm ethereal!
