Dream of

I had a dream that there were people who were killing God's people . I started praying and there appeared a girl who slaughtered one of the killing people with a knife and too much blood sprinkled on air. I started singing to God then heaven opened. I saw an angel putting a mirror in an open heaven so they were watching evil ones who could kill God,s people and were protecting me and other people .It was only me who was seeing open heaven others were not seeing .
