This incident is happend 7 years ago. when I was in 8th class we planned to celebrate a pot festival in our school. It was Sunday our school is closed and no body is there in school me and my two friends are came to school by jumping the compound wall. We went to our class room. Then only I went to washroom on 3rd floor. I know that time is 9pm . I entered into washroom and I closed the door. then I noticed that somebody opened the Tap but I think that my 3 friends went back to home by 7 pm. The school is filled with silence but I can clearly hear the footsteps sound and I can hear some body knocking my door. My heart is ready to skip out.then suddenly power went off.and 5 mins later I opened the door and slowly started walking power went on then I noticed a palm symbol with blood on mirror I started running and went back to home. After 2 years at our final exams time I took one of my friend with me to washroom. then there is an maid in our school washing washroom. She said to me that y are u using this washrooms.there is a devil revolving here who was died in house at these place which was replaced by our school .then I remembered the incident of that Sunday night which happened 2 years ago.then I realised that .first time I got fear . 7 years paused now I am completed my btech. but even now also that haunting place made me many sleepless nights for me.
