The somewhat dreary history of casual games goes something like: First there was Bejewelled, then there was Diner Dash, then there was Mystery Case Files. Virtually everything successful in the field is essentially imitative of one of those three: match-three games, time-management games, and hidden object (aka "hunt the pixel") games.
Naturally, we do not cover such jejune and imitative dross; Dream Chronicles is, however, original and interesting enough to be worth a look. It does have a "hunt-the-pixel" aspect (there are "dream pieces" in each location you need to find and click on to assemble a "dream jewel," and doing so gives you a clue to a puzzle), but it's not core to the gameplay.
