I had a dream of this song from the 1989 film version of The BFG being sung by Princess Luna in MLP sometime last year. I don't know why, but it was beautiful, and it inspired me to rewatch that awesome animated movie of my childhood. Every time I listen to this song now, I'm reminded of Luna and her power to enter the dreams of others.
In fact, I feel this song would fit Luna very well if she ever sung it in the series. I would even at least like to see someone make a fan animation of Luna singing it. Maybe we should contact the one who did the fan animation, Children of the Night, and get him/her to do a just that. And have Kate "Erutan" Covington (Katethegreat19), the same girl who sung the song, Come Little Children in Children of the Night to sing this song as Luna.
