I'm Dreaming of a Blue Christmas

I'm dreaming of a blue Christmas
Which does sound kinda odd I know
No last-minute buying
And simply flying
My own ikran over the snow

I'm dreaming of a blue Christmas;
In my mind I've taken flight
With the Na'vi who are awesome and kind
Unlike humans, who aren't especially bright

I'm dreaming of a blue Christmas
It is impossible I know
The whole thing is fiction
But my imagination
Don't give a (rude word here) (1) 'bout that

I'm dreaming of a Blue Christmas
Even though Pandora's very far away
But if you see a spaceship
Talking 'bout peace and fellowship
it's probably them coming to stay

This is part of a challenge made by my circle of Fanfiction friends to make up Christmas carol parodies on certain subjects.
Just to let people know I do swear, I just needed the line to scan :-)
