I liked it. Nice music and art. Albeit short it's pleasant and I really like the combination of art styles. Turning white surfaces pink is also a nice touch. I'm not sure if I'm supposed to touch all the white surfaces to unlock something? Because I didn't. Too much work hehe.
Regarding your artistic statement. You can better remember your dreams if you keep a dream diary! The trick is to not get up and move after you wake up from a dream and you will remember it much better if you write it down before leaving bed. It is also possible to control your dreams via lucid dreaming. I have never done this myself though it is possible for anyone to achieve lucid dreaming with enough practice.
