The two are parasitic sisters who infiltrate dreamers in the middle of the night. The Creator designs nightmares and implants them in the minds of innocents. After terrifying the host, the Snatcher comes in and fights off the monsters, drawing energy from the defeat. After all the energy has been leeched from the host and the demons defeated, the Creator chooses to either replace the horrors with pleasantness, or leave the memory be. She often gathers more strength from replacing it with pleasantness, and chooses to go that more often than not. However, occasionally, she will decide to leave the nightmare be. On those insentience, the surge of energy is quick and sweet, but fades quite quickly.
