I don't know if it's missable or not, because I didn't know about this #10 being triggered.
I did that earlier, while I searched the doll, but on the way back, it DIDN'T trigger. What did I do wrong ?
I completed this mini-game, but it didn't trigger the dream #10.
Maybe this one is the only missable dream ever.

Please, update this post. You need to hug the right side of the bazaar near the corner to be triggered. It's not missable.
Edit 2: Unlocked this Achievement. You don't need to read ALL the dreams. Just skip them by pressing the B button. All you need to do to unlock it is to trigger all the dreams.
