I've played four different "IQ test" games and I've obtained the same score in all of them, wich was the exact same I obtained in an actual IQ test five years ago (132). I don't know how such an aparently arbitrary test can work, but hey, great work you did there.
The text of the 15 notes: "I first encountered this phenomenom in the early 80's, but it would seem They have existed since the dawn of the human race. Commonly known as the Night Folk, or Shadow People, they live in the realm of dreams, but desperately want to get to our realm, by possessing vulnerable, unoccuped bodies."
As long as you dont know you are dreaming, you are save... They attack when they sense a mind detached from its body, wich sometimes happens durig comas, but much more often during OOBEs and Lucid Dreaming.
P.S.: Did you know you can unlock a secret ending by placing the Plushie Tiger on Cody's Bed?
