To give credit where credit is due, the theory was first born from reddit user EatRayLove, drawing parallels between the content discussed in Split to one of the director’s earlier works.

The film that put Shyamalan on the map and one that has stood the test of time since its release in 1999, The Sixth Sense is the story of Cole, a young boy that can communicate with ghosts, who undergoes treatment from psychologist Malcolm Crowe by request of his mother. Figuring out his gift and aided by the doctor, it’s discovered at the end of the film that Crowe himself was in fact dead all along, killed in a sequence earlier in the movie that had been passed off as just an injury.
Now, the link between the two films comes from one key moment in Split that can be interpreted in a number of ways.
