It's just about my hat

I couldn't find my hat to wear
For bed last night 
And it was blowing a gale 
And freezing cold
And I can't close my window 
Coz I get claustrophobes 
And I can't close my curtains 
Coz I don't like the dark
And I have a little light
But then they think it's day
And it's not time to play
And my face felt like ice 
And my nose was like Rudolph 
The reindeer 
So it's seems pretty clear
That I need to find my hat
For bed tonight
