So I have always thought I owned the realm of the "ethereal", since the concept for me revolved mostly around the movie "The Dark Crystal" which I watched countless times when I was 8 years old. I always wanted to be Kiera...that gorgeous little blonde gelfling who wore those amazingly raw art nouveau'esque clothes and who had wings....(I also had a crush on Jen...but we all had crushes on a muppet thing at 8, right?)
Another key movie that influenced me at an early age was a movie called "The Last Unicorn"...I wanted to also be the ethereal blonde (again!) unicorn who had been transformed into a human.....
This film used to make me cry....the girl who had be changed into a human was growing weak and had to be changed back into a unicorn even though the magician who transformed her fell in love with her...!
I spent so much time drawing unicorns and flying horses and fantasy creatures. My mum even made me my own Kiera dress, and I think I remember complaining it wasn't 'raggy' enough....
I have always considered the concept of the ethereal as meaning 'otherworldly', or heavenly...which I quite love.
