One of my friends once told me on the phone that he could hear voices in my background. He asked me to move to a quiet place so that we could talk. It freaked me out because I was alone in my hostel room and there was barely anyone left on that hostel floor since everyone had gone home for holidays.
I later found out that he was just pranking me but it was pretty effective since I had just seen ‘The Others‘ and was in that phase.
This video by TroubleSeekerTeam tries to capture something similar. The guy takes his girlfriend out for an evening and it leads to a NH10 kind of scenario…almost. (or not 😛 ) Check it out!
