I read Paul Tremblay’s highly acclaimed novel, A Head Full of Ghosts, a few weeks ago and still find myself thinking about it. That’s high grade voodoo right there. Book is straight up haunting me.
Therefore, I’m not only writing this in an attempt to explain what’s causing it to linger, I want to get this shit 
out of my head.
On the surface, Tremblay’s book is a fun, entertaining story about a family dealing with a daughter who is either possessed or mentally ill. It’s told through the adult recollections of the possessed girl’s younger sister. Recollections that appear to be somewhat confused, and almost certainly unreliable. This woman is traumatized by what she experienced as a child, even if she doesn’t realize it. Pay attention to the way the woman she’s narrating her story to is reacting and you can see how strange and damaged she’s become. For me, that’s the most horrific part.
