hi I am karan. Well I want to suggest you a word "hallelujah". Its a very powerful word. If any demon comes near to you say this word loud, the demon will fly away from you or burn. Another thing is that before you sleep say "The Lord's prayer"which is in Bible. Another thing is that before you sleep imagine a royal purple light covering you and your family as purple is archangel Michael's colour. Just tell me that we all are the children of God then howcome demon is more closer to God than us. Just remember one thing that where there is God demon can't stand there. Hope this helps.
