Packed Lift in Genting?

This is a story told by my sister, she was working in genting and knew this boy who happened to hv special ability to see and hear ghosts. His mother who has the same ability able to close his Heaven Sight but his hearing ability cannot be closed. From tht moment onwards, this boy can hear people whispering or gasping for air heavily. This story begins when this boy and his 7 other friends were in Genting Highlands. One of his friend, a girl who can see ghosts also was in the group. All of them went into a lift to go to higher floors. As soon as they went in, the lift starts to warn for heavy lifting. Ding Ding Ding....although only 8 of them in the lift. The instruction in the lift states that the maximum number of people that can accomodate a lift is 21 people. You know what i mean...it is believed that if u encounter sch unexplainable situations, do not tell right on the spot. This is what one of the girls did. She was freak out and keep on saying 'what happened? why like that? so scary!' The boy and the girl who can see ghosts ask her to shush but she still keep on repeating the same sentence. They left the lift and scolded the girl for being so talkative-about-ghost. That very night, the girl dreamed of many ghosts chasing after her.
