Big apology for the confusion. We're definitely in agreement that the game needs more clear instructions.
You essentially got it in that each ghost pairs with another ghost. They key is that once you know which ghosts are a pair, you also have to figure out which SINGLE piece of dialogue from each fits together. So to take the artist as an example (spoiler/hint ahead) the two artist ghosts are telling different parts of the same story, but each one has a piece of dialogue that directly references being old and crippled. Combining those two will make a ticket. Same case for each other pair of ghosts; you're looking for the pieces from each story that most closely resemble eachother.
