Lighted Candle

I was wondering what it means when a candle lights itself? When I was down at my daughter's place sitting at the coffee table in her living room and she was busy changing the baby's diaper on the floor and then, we heard a little dribble at first and turned around and the candle lit itself. I had asked her when she used that candle last and she said she used it last Christmas so it wasn't lit recently so there so why did it lit itself? And I almost forgot, she does hear voices of children in the house at times and she told me she heard someone walking up the stair way in her apartment, and cupboards doors slamming. She also claims a man breathed in her ear. She claims or is sure there are children and a man maybe haunting her apartment. We don't know anything about her place who was living there or anything. I don't know what else to say but I wish we could get answers and point us in the right directions. I wanted her to get the house bless. Or something to see why she's hearing voices and candles lighting themselves. We won't to know what is going on and just looking for suggestions on what to do, My daughter fills threaten and is scared something might happen to her or her children. And with this candle lighting its self does it mean death or is her house going to catch on fire. Well I don't know what to say I think I have pointed out everything, I could I have nothing else to write but looking forward to hearing from any one that might have a answer to this Question. This is all true to my knowledge.
