0ne mid night in the winter while i was in deep sleep, felt like someone cought my neck and press it so hard...I hardly breathed...That had last like 20min..Then i realized that devil has gone because of that wonderful golden light coming in from the window..I awoke up and saw my room was flooded with that light...I had seen it for like 10seconds...As i run to my window to opened up curtain to see,it disappeared..I always thought what was that light and where it comes from!
