No no... look closer at the word "Catherine": it has what seem to be very specific breaks in how the letters come together. Almost like it says "C at he r i n e".
So, the first part: "C at he". C, aka "see", aka look. "Look at he" or, more exactly, "look at him". Saying that we think Catherine is a female, but if we really "see" her, we'll realize that she's a he. Then, the next part: "r i n e". "R", or "are". "i" is of course "I", or a reference to the both the main character (storeline-wise) and the player (control-wise). "n", or "in". And then finally "e"... which, if we think about slang, "E" is shorthand for the drug ecstasy.
Thus, the second part is "Are I in ecstasy", which seems to be a question the character - and the player - will both be asking themselves. So, we may initially think that "Catherine" is the name of the game, and the name of the main female character, but it's also hidden code revealing one of the main elements of the game: if we see Catherine for what she really is, when that truth is revealed to us, we may find ourselves obtaining the desire we've longed for but never really knew we had.
