For the duration of the day characters are trapped in a dream world. They can move in and out of other people's dreams, but they cannot wake up. Players decide if their characters' dreams are to be only observed, or if characters can interact with the dream.
See no Evil, Hear no Evil, Speak no Evil Day
Characters wake up only to discover that they are either blind, deaf, or dumb.
Power Switch today We need switch days like we need global warming. :P On this day character's have their abilities switched around with each other. Those who don't have power may suddenly gain some for the day, while those with power may wind up without any.
The Road Not Traveled Day
Every character is defined by the choices they have made in life. But what if your character had chosen the other choice? What if Alessa had decided to bring the god into the world willingly? What if Flauros had never joined Letumael?
On this day; the characters act how they would had they made a different choice at a pivotal moment in their lives.
Movie Quote Day
Characters constantly quote lines from movies even if they've never seen them; and they do it often; and they do it at inappropriate times.
