Great choice to use dreams as a setting - whole tone has often been used to simulate a weightless feeling, and you captured that really well, especially in Dream Walking.
The two pieces didn't feel all that connected to me, like quite different games; they might have made sense in a larger OST, but as two tracks they felt a little disparate.
Don't get me wrong, I really enjoyed both pieces, just talking about the overall theme/intention of the 2 tracks :)
