Note to the reader.
I know that Erik doesn't act in that way, I know Christine didn't write the storey, but it's just a storey ok, it doesn't have to be perfect (and I haven't seen Phantom of the Opera since I was 7 ok). Also in the flash-back Tikal is 8 and in the now Tikal is 12. The dreams are supposed to be confusing but you should be able to work it out after a little while.
Tikal is 12 years old and she looks like Anjou from Karin besides the fact that she wears what looks like a plain pirate patch over her left eye because it's red like a devil's eye.
This is somewhat based on a dream I have had in my past that is too hard to explain.
P.S: Did you know that The phantom of the Opera was a true storey?
