What an awesome entry ! The graphics are beautiful and I like the concept of your game. The ambiant music sets perfectly the mood and the story-telling was also very nice!
My only complain about the game is that it took me a while to understand the swap mechanic : I thought I could swap at will, when, in fact, I can only swap to go to the dream world for about 5 seconds, and it bring me back to the real world automatically. I struggled a lot with that mechanic, I would have loved a visible "dream world cooldown" to know exactly when I'll be back to the real world.
Overall a very solid entry, especially for a 7days jam, congratulations !
