Wake

In the novel Wake, the protagonist Janie has the power of entering other people's dreams. In the dreams she enters, Janie discovers the secrets of her friends which she doesn't know in reality. The book's idea is similar to Inception; it also shows how humans tend to hide their dark side. It is very interesting to see through Janie's view how people who really look confident in real life are actually cowards in the dream world. If you like Inception and think you would enjoy entering into the dreams of random people, Wake would definitely be a top choice.
