LA UNION - Five students of a public school in San Fernando City, La Union were allegedly possessed by evil spirits after taking "selfies" near a duhat (plum) tree, which locals believe is the spirits' home.



The principal said the students suddenly became hysterical while classes were ongoing.



The possession started last week after three female students took a selfie under a duhat tree at the back of their school.



It is believed that they stepped on and destroyed the spirits' "home" after taking photos.



The principal said she has already asked as local priest to bless the classroom. She also said the students are undergoing stress debriefing.



A psychologist said the students may just be suffering from physical, emotional or psychological problems.



"My tinatawag kasi tayong alteration disorder. Yung baka may problema sila emotionally, baka nagsi-seek sila ng attention na hindi nila nakukuha sa bahay kaya nangyayari yun. Pwede ring yung physical aspect and mental aspect,' Dr. Estrella Perez said.
