We used to live together in the hostel, it was the midnight and the next was our friend's birthday so me and my friends leaving him decided to scare him at midnight of his birthday and surprise him with a cake on the terrace. So, at the midnight started to scare him by turning of and on of lights first in his room and then when he will come out it was the turn of corridor. We didn't expected that he got scared this much, then after some time when he was running around in the corridor shouting for help, we had already planned no one will help and neither to open the door of there rooms. Then we started to turn off lights one by one of the corridor, he was really afraid of darkness we knew it that day, then he ran towards the terrace as per the plan and then it was the time to surprise him with his birthday cake. When he came to the terrace we cheered him up that it was nothing with the hosted and neither it is haunted, we then said him that it was just a prank and wished him Happy Birthday. After this mischievousness, the security guard came up to the terrace and shouted that what was going o, we then explained him that it was our friends birthday and we were just doing a birthday prank on him and surprisingly he joined us at our friend's birthday celebration.
