A strange situation in my life

I was cooking in the kitchen with my sister last night, when suddenly we heard a strange noise like a great crash, we stopped cooking and walked to the living room to know what happened. It was very strange because the light turned off. However I turned on a candle, suddenly we saw a ghost woman trough the mirror, she was very ugly, because her face was like a skull, she wore a dress of white color; on her head she had crickets and black butterflies, my sister was really frightened and me too, we prayed and ran so far away... I didn´t know from who were that voice.
