I'll Be Home For Christmas lyrics

Memories of nyc and my childhood dreams of a white christmas

Home is where the heart is... Everyone wants to be where love light gleames on christmas eve.. The spirit of humankind longs for this place... For many, it is only a dream... If you are actually in this place, consider yourself fortunate

He's just letting his loved ones know he will be with them on christmas, he wants everybody happy and decorating like normal. In the end where he says "if only in my dreams", you realize that cant physically make it but his heart is definately there.
This happened to me when i was 19 and stationed in berlin. I couldnt get home untill after after christmas was over. It was the worst christmas ever. Especially for someone that always spent it with their family. I also feel that we spend it remembering the ones we have lost and can picture them so clearly smiling and laughing with us on christmas' passed. In my mind i will be back home there as well.
