Spirit Desperate For Attention?

I've always lived in houses that have had some kind of spiritual activity but nothing major. It was usually just little bangs in the middle of the night or the tv turning on when no one was in the room. When my family started building a house in a field we found out that the field behind us was an ancient burial site but we thought nothing of it.

We moved in 8 years ago. Within 1 month of moving in we heard what sounded like 2 men having a conversation in our sitting room at about 1 o'clock. They were speaking very fast but I could tell they were speaking fluent Irish. My father went downstairs with a hurley stick but when he came back up he said there was no one there. We kept hearing them but each time there was no one there.

After about 2 years it escalated. My mum was putting my brother to bed and I was reading in my room. All of a sudden we heard a crash downstairs. We all went to see what happened. At the top of the stairs we could all see. A picture of my brother that was in the sitting room was lying smashed in the hall. After that me and my brother started having nightmares. They were similar. We both dreamt of 2 men and a small child with their faces covered in either my bedroom or the sitting room. The dream would always end, for me, with the child screaming and with my brother, the men taking off their masks off.

Very recently my mum was in the shower, my dad and brother were asleep and I was in my room with my cat playing on my computer. My bed is in the middle of my room and I was sitting at the far side, away from my door. Out of the corner of my eye I saw someone walking into my room and lying down on the ground at the far side of my bed. The person was short so I assumed it was my brother and told him to get out. There was no response so I gave up and went back to my computer. All of a sudden it went off, even though it was charging and wouldn't turn back on. I got up and went to the far side of my bed to get who I thought was my brother out of my room but when I went to the other side of my bed there was no one there and there was no one under my bed. I got up and went into my brothers bedroom where he was sound sleeping. Whoever it was was too short to be my mum or dad and I was getting a bit scared. I went back into my room to see my cat acting weird and making weird sounds. All of a sudden my cat turned to me and started to scrape at my legs. I ran out and closed my door until my cat stopped making weird noises and when he did I saw he was sound asleep on my laptop.

I was wondering if any of you know what kind of ghost this is or what is going on. I think this ghost wants attention but I'm not sure. Either way its starting to scare me.
