I was walking back to home from my friend about ten years ago. it was around 9pm and i was about to call my mother for saying i'm sorry for staying out without telling her. suddenly a bright light caught my attention, i looked up to the sky and an oval-like object which looked like pure light with smooth surface was charging towards me very fast. i didn't dare to move and when it was around ten meters from me, it slowed and came slowly close to me. it hovered and circled around me for a bit over half minute. it was about thirty to forty centimetres away from me and light from this light-like smooth object felt cold. i raised my hand and intended to touch it but when my hand almost reached it's surface, i heard this very high pitch voice i couldn't bear. the voice lasted for a couple of seconds before the object launched back to the sky, disappearing from sight in two seconds.
