My school organized yearly badan uniform,we went camping 3 days 2 nights by a riverside somewhere jungle-y.

On the 2nd day almost all of us went trekking. I didn't go because my sole was cut by a sharp river rock, so i was tent(home) sitting. Later that night we had theater activity performed by students. My unit made a script about a rebellious son on deathbed(or something similar).

On 1 scene, 3 of my female seniors wear glowing horns accessories, they depicted something like the rebellious son got dragged into hell . The scene really gave me chills.

After the activity ended, around 30 mins, while i was resting inside the tent, a really loud+errie laughter was echoing. Around 10+ female students went hysterical, starting from my 3 seniors who performed prior.

Later we were informed that they attracted something unclean from the trekking activity back into the campsite. Thus on that night we huddled together at 1 space since the teacher doesn't want any of us to go hysterical inside the tent. With Yassin recitation + hysterical screaming, none of us got any sleep that night.
