Cold+Halloween+Night

It was a cold Halloween night when I saw the swing in a park near my house. It was nothing special if there was someone sitting on it but looking around, I didn't see anyone and I still heard some whisper. I could even hear the sound of the swing was moving with no one pushing it. I realized I was very scared because I was standing alone in the middle of the night. The weather was freezing. I wanted to run away immediately by that time but my legs seemed to be paralyze and my lips were sticking together and I couldn't say anything

Even more scared, I saw a white shadow passed across my eyes with long hair, feet didn't stand on the ground like me and when it passed through me, I heard a laugh "hahahaha..." So scared, I turned back to define where the laugh came from. Cannot believed it, there was the scary teacher...
