Apparently OkameP used Gumi's version instead of his Miku version in the album, so I'm a bit confused why nobody bothered to upload the this version of this song individually yet.

Miku's Version:
   • 【Miku Hatsune】Dreams and Visions【Engl...  

Full Album:
   • Hatsune Miku, IA and Gumi - Cockatiel...  
The album is free. There should be a download link in the description of this^ video.
