Ghost in a Boarding School

I went to this rural school at the age of 12 years , my school was build on top of grave yard , people say that our head master was desperate for money instead of looking for people to properly dig the graves out, He just ask some contractors to remove the top of the graves and start building .They build a day school and on the another side they build a boarding school . Boys and girls sleep from different rooms and lights were turn off at around 9o’clock . That’s when things began to happen .I remember hearing the door opening slowly ,then I quickly cover my face with my blanket, my heart start beating very fast like horses running the race, then a cold breeze pass through my bed , go to another room , Before I knew it I fall into deep sleep and Before we knew it, it was in the morning because our head mistress was ringing the bell shouting” wake up wake up every one” . we all wake up go to bath, Since we were not allowed to talk about what was happening but I had to be brave and ask my friend if she heard any thing strange last night and she said yes by whispering and looking around to see if no one has heard us and she said the ghost open her blanket slowly and spit on her face, but she told me that she over heard another girls saying that they have seen a light of fire in the school garden , moving from one place to another then little small fire appears behind a big light following the big one. And when they go to see if the grass has been burn in the morning there was none. The ghost visited us every night throughout my stay in the boarding school, we got used to them and I believe they knew us because we both knew that we don’t pose danger to each another. But it was total different with the Boys they did not wish for the night to come they hated it , scared because their ghost was not friendly with them it will shook their beds and through out the night , they could hear people talking and loughing at each another oh boy ! oh boy! .
