We're dealing with a lot of different factors of freedom and confinement in The Curious Incident of the Dog in the Night-Time: physical, mental, emotional, and even spiritual. At times, these factors are oppositionally related – that is, more freedom in one means more confinement in another. For example, Christopher thinks most clearly when he's hidden in tight spaces: physical confinement results in mental freedom. His emotional state is trickier, because he's by nature closed-down and internally-focused. His spiritual life is, in one sense, one of boundless curiosity and depth, and in another sense, one of narrow judgmental ridicule. Ultimately, we could say that Christopher's freedom allows him to be confined, as much as his confinement gives him great freedom.
