Welcome to the dark side

From school time we were friends who knew each other, but never really talked or spent much times together.
Our great grand aunts knew each other and once a year I would visit her.
She was always nice to me and I knew she liked me a lot.
From my great grand aunt I would hear, - Julia always asks if you are going to visit.
Then at her house we would have nothing to talk about.
Sometimes at night I would watch her playing with small candle fires near mirror in her bed room.  She was talking to it, moving softly hands and smiling.
One time I got scared and next time, she would put Bible in their living room..
