Throughout midnight

I have scared midnight, yesterday! I studied from 11 pm until 1.30 am. It was very spooky. When I was studying, I heard a sound like the sound of chicken. At the beginning, I didn't care about it, but there is no chicken in round my house (included my neighborhood). I remembered what my friend said about the spirit of a woman who has died in childbirth (Indonesia's original ghost or spirit, Kuntilanak). "Kuntilanak's sound is like the sound of chicken. Kuntilanak isn't laughing, but she is crying" said my friend.
I immediately ran to my room when I realized would the existence kuntilanak apparently was going for a walk in front of my house. I could not sleep several times because I continued to hear the voice someone was jumping in the ladder of my house. This voice disappeared when my mother got up and I did not dare to tell this hair-raising matter to him. A few moments later I fell asleep was sound asleep until made me late to the school.
