Corneal transplant, check.
Overdose sleeping pills, check.
Practicing how to see a ghost from a book, proceed.

Now I'm confused, I thought something like bending over to look back between your legs or brushing hair at midnight in front of a mirror was urban legend or how to see ghost that originaly from my country, so it's not but it's turns out it seems to be comprehensive in southeast asia.

For the film overall still fun but not creepy, instead only the comedy sticks in my mind. That dance battle in the apartment will be remembered.

When I think about it again, the film is indeed more pursuing to be funny, the horror aspect is not the main thing. They even parodied the iconic elevator scene, and it was hilarious. But unfortunately a parody is not something I expect from the conclusion of a horror film trilogy.
