The Old Man's House

First off, I'm from Adelaide Australia, I'm a 19 year old girl and I can be a little skeptic about ghost stories and such because they can be blown out of proportion all too easily. But this is my story and I hope you can help answer some of my questions.

When I was three years old we moved into a new house, it was built in 1911 and only one family ever lived in it. The man, who lived in the house before us, was the son of the man who built the house. He died in the house when he was 82 and that was six months before me moved in. It's an old, one story brick house with a small wine cellar. My current bedroom was his old bedroom and when we moved into the house, there were bars and chicken wire covering the windows (he was agoraphobic), all of the other windows had heavy, metal bars on them but didn't also have the chicken wire. He didn't die in my/his bedroom; he had a heart attack in an outside toilet that's not longer there.

I started having nightmares as soon as I was moved into my room, but whether this is because I was young, if the change disrupted me or if the room had an eerie feeling I don't know, probably all put together. I used to wake up in the early hours of the morning (I was talking to my mother and she said I had a knack for waking up every night at three am, and yes, I've heard what people say about three am but I'm not 100% sure I buy into it.), screaming, crying and extremely cold even if it was a warm night and I had blankets on. This carried on until I was 6 until my parents gave up on thinking that I would grow out of it and I slept in my parent's bed until I was 10. Just after my 10th birthday I wanted to try sleeping in my room again, but by now I was able to recognize that it had a strange, cold feeling to it. Even my father, who is the biggest skeptic I know, agreed.

I continued to have nightmares but now I could remember them, it felt like I was in a room with everybody and everything I loved but every time I tried to touch anything I would feel this soaring pain through my chest and I'd screech and cry in my dreams. After I woke up I would calm myself down and go back to sleep, wanting to be a big girl. After about a month the nightmares stopped, or I just slept through them.

When I reached the age of 12 I started seeing three apparitions that would all come at the same time. One was of a man hunched over and he would be close to my bed just looking at me with this blank, dark eyes. The other was of a tall man, in a priest's outfit who was slowly coming toward me. The last one was just a face, floating in mid air with a scratch on his eye and a bruised lip. The thing is, it was all the same man and they all had the same face, I'm certain of it. And it was the same every time.

After about a year, when I'd finally convinced myself that I wasn't making it up I tried talking to the hunched man near my bed. But as soon as I uttered my first syllable (even at the time, I'm wasn't sure what I was going to say) he let out a screech, the same as I heard in my dreams. The next morning my mother asked me if I'd had a nightmare because she'd heard me screeching.

I've never really told anybody because I was nervous people would simply think I was making things up because I was a child. I don't see the three ghosts as often anymore but lately I've been having my old nightmare again and I was looking for a couple of suggestions as to why they might have started again? And what are your opinions on seeing the same man as three different apparitions? Anything you can tell me would be a great help! And sorry this is long, thank you!
