When I was 16 years old I was at my friends, we were abruptly awoken by the sounds of pots and pans bashing together in the kitchen, so we went and looked and nothing was there but a shadowy figure and only for like a second and it disappeared. I went home and told my mom about it and she had me take her to this friend's house. She went completely white so I asked her what was wrong. She explained to me when she was pregnant with me she and my dad lived in that house. She said they always heard pots and pans banging together dramatically and there would not be anything there. She would also hear things being thrown right outside the windows and she would look and nothing.
But the one thing that made her and my dad leave in the middle of the night was one night when they could hear a little child. She said it had to be about 9-10 years old and was running back and forth in the attic. You could tell the little kid was playing with toys. They immediately left and went back the next day to get everything they owned and my dad decided to look upstairs because everyone told them it was probably a racoon or something. It was completely dusty, not one footprint, not anything. I find this very peculiar now that I am older and when I sit back and think about it, why 16 years later would I be at this same house that scared my mom and dad half to death and why would it let me see it's shadowy figure and not them? Was it trying to reach out to me? Should I have went back? Should I go back?
NO! Leave well enough alone. You already know that there is something there, so don't go back to that house. Pray and ask the Lord to surround you and your family with the white light of the Holy spirit and leave it alone. You don't need anything to attach itself to you and follow you to where you are living right now. I will keep your friend and her family in my prayers as well.
