So I might have to break this story into two parts, and have to bring about a little back story to make sense of it all.
So back in either October or November of 2007, me and my family (mother, father and younger brother) all moved into our very own house. The house itself was more of a shack, it's old and was in fact once a banana packing shed. Prior to this house, the house we had lived in was in fact haunted, confirmed by myself and my mother both feeling a presence and her actually seeing things and being touched. Anyhow, we had just moved into this house and my grandfather (mother's side) had fallen ill, so we had to travel to New Zealand to say our goodbyes, and unfortunately, he had passed away while we were on the plane.
Fast forward to December of 2010, I came up with the idea of going to New Zealand and spending Christmas with all the family as most of them live there. The entire time we were there I could feel my grandfather there. Like I'd sit in "his" chair and I could still smell his cigarettes. My father, brother and I had all gone out to where my other grandfather (father's side) is buried. My father placed a coin on his grave and said, "Come visit us sometime, Dad." I think this is what caused most of my "troubles".
Now moving on to my actual paranormal happenings. For the first two years of living in my new house I never did have anything happen to me. It wasn't until I was about 14/15 years old (2011) that something started happening. It always felt like someone else was in the room watching me, and it never did feel good, it always made me feel uncomfortable. I believe it was mostly attached to me because, at the time, I was going through very bad depression. Another thing about this house is that it always had this negative feeling because of my father's abusive ways and his temper.
At the end of 2013, we had found out my father was cheating on my mother and so he moved out and some of his negative effects had gone with him. Anyhow in May of 2014, I was 17, I had finished high school the year before and I wasn't doing anything with myself due to my depression being so bad it was weighing me down. My mother decided to kick me out and I went to go live with my father. My brother then decided to move into my old room as it was twice as big as his old one.
About 6 months later I had moved back in with my mother, into a room off the house, and in a better mind set. My brother, on the other hand, had succumbed to depression and anxiety. It was once after I was moved back in, I was talking to my mother and I was telling her about how it always felt like there was someone watching me in my old room. My brother happened to be in ears shot when I was telling my mother this and he said he felt a similar thing. He also told me of how he woke up, paralyzed and he looked at the end of his bed and he said that there was this big black demon-looking thing with torn clothes. He said it was only there for a few seconds before it like disappeared into the ceiling. My mother and I agreed that it could have been my grandfather, as I told her of my father asking my grandfather to visit.
At the beginning of this year (2015) we were looking at places to rent, as we had sold that house and were renting it off the new owners. We had looked at the house we are in now and both my mother and I had such a good feeling about it. We've been living here for 4 months now, and I feel like whatever was in that house has stayed there. All I feel around me now is good entities, which me and my mother believe is my grandfather on my mother's side.
I'm still not sure if it was my father's father, or something else. But I do believe it has now left us alone, and I forever hope it does.
