Broadcast journalist Atom Araullo investigates the mystery behind various incidents of possession in an elementary school this Friday (Jan 31) in “Hiwaga.”

What seemed like an ordinary day for the students of a school in Osorio, Cavite, quickly turned into a nightmare when some students and a teacher became victim to so called sanib or sapi.

Measures had been done before, according to the teachers, such as going to albularyos or psychiatrists. But despite their efforts, the possessions went on and even escalated.

In January of 2014, six students and a teacher had fallen prey to the possession. It was said that spirits who used to live in the trees that were cut down to make way for new classrooms were the ones causing the disturbances.

When the “Hiwaga” team came to investigate, a student by the alias ‘Raymond’ appeared to fall under possession when he came to the principal’s office bearing the numbers 666 on his arm, writhing as if his hands were being held down, and having unnatural strength.

Will paranormal experts be able to stop these possessions and appease these spirits?

Don’t miss “Hiwaga,” anchored by Atom Araullo, this Friday (Jan 31), 4:45 PM on ABS-CBN’s Kapamilya Gold.
