Have you ever seen the Carrie prank? If not, now's the time to watch it, because it includes a dynamic public prank that scares the unsuspecting customers to death.
(Carrie prank)
As the victim sits in place and wait for the teacher, the actors make their way into their seating. After around ten minutes into the lesson, an actress wanders in, wondering around looking worried. She starts to scream, "Where am I?!" and starts to look delusional.
"WHY CAN'T ANYONE HEAR ME?!" As the victim starts to understand her and approach her, the actress starts to freak out, claiming that they must be dead. The victim is lead to an identical version of the lost girl, supposedly dead, and is tricked into believing that the girl is dead.
"You're the only one that can hear me" or "I thought I was alone" or something along those lines to make it seem lime the victim is dead. This is repeated several times with several victims, all of the reactions being secretly recorded.

The idea comes from the book where Mia is a cello player who is in a near-fatal car accident with her family and is in a comatose state as she witnesses many things that change her life forever, but nobody knows that she is there, so she is suffering but she doesn't have someone to help her. The choice of her living or dying is completely up to her, like if she is confident she wants to live, then she will, but if she wants to let go, she will.
The cello studio is reflected on her playing habits, as she is going to Julliard for her cello playing. The ignoring of everyone is from her being completely ignored by everyone surrounding her just like in the hospital, and the woman who can hear her (the victim) slowly realizes that she might be dead or comatose.
"No! Stop! Please stop. Please... wake up." (Forman 18) Mia refuses to accept the idea, but she is in a comatose state and that nobody can really hear her, but she just wants to wake up.
"Am I dead? I actually have to ask myself this. Am I dead?" (Forman 19) She's starting to believe that she isn't who she was looking at in the car, that she was in a state where nobody knew she was there.
"I see the glint of silver of my cello charms. Adam gave it to me... It's my bracelet." (Forman 17) She starts to realize that she is in a bad state, but is still confused over why she can see herself in two places.
Mia is starting to realize that nobody can see or hear her, as well as in the prank where nobody except the victim can hear her and it starts to scare the victim even more when the prankee sees the body. Its is almost implied that the actress is seeing her body for the first time as well, and starts to freak out about that.
I think this will work because the people being pranked will understand the feeling that Mia had when nobody could hear her, making them really feel the plot of the story. It will be an entertaining way to stimulate the reader's who know what the story line is about.
