The Me of Yesterday
In your dreams (an eternal white staircase leading infinitely up), you interact with the you of yesterday. You don’t know what happens outside of the dreams, but depending on how your day went, yesterday’s version of you will be in different moods and environments. Interacting with yesterday’s you shapes how your next day will go. At the end of each dream, you also have the option of killing yesterday’s you to simply forget yesterday.
Balloon Seller
While at a festival, you meet a balloon seller who sells balloons filled with memories. They come in different colors and shapes such as bittersweet, nostalgic, that-thing-I-really-should-remember, etc. with prices that change relative to importance. Spending time with him as he sells memories to other festival-goers lets you see why he chose his profession and how other’s react to remembering what they’ve forgotten.
