My Ghost Used To Be Subtle... Not Anymore

I live in an up/down double. Mother lives downstairs. We had a family dog that always slept at the foot of her bed in our previous home. Upon moving into this home, the dog would NEVER go into her room or even the hall leading to it. For two years it slept in the living room or dining room NEVER going into her bedroom.

My mother downstairs and I up, would always hear noises and have odd happenings. Lights turning on/off, phone ringing with only a dial tone after answering, ceiling fans clicking on. Leaving the room and coming back to a candle being moved from one side of a table to the other. One day my mother spoke to whatever was there telling it to move on, leave, etc... THAT NIGHT and from then on (2 years after moving in) the family dog began to sleep at the foot of her bed again and she has had no dealings with them.

It's been about 6 or 7 years since that incident. We still hear noises, I normally hear them in the attic, but they never bothered me. My mother would hear things at my place upstairs when I wasn't home. But, like I said, they never bothered me until now.

At night I get the same knock every night. One knock...pause...two quick knocks. They move from one corner of the room to another. One night four loud bangs on my bedroom door followed. For eight years something has been there, but now it is becoming more aggressive. I didn't notice after the first few times, but if I am asleep prior to 1am, either they don't bother or I'm just out like a light and don't hear what is going on. But if I'm awake, trying to go to sleep past 1am, it will continue for hours. Always past 1a.m! The same knock on the wall to my right, then to my left. Once it felt/sounded as though it was on the foot of my bed! I don't know if it is from my increased heart rate (after they start... The hair on my neck/arms stand straight up and my heart races) but when this starts to happen, it gets unusually WARM in my bedroom.

I am now to the point where I'm not ok with this ghost or whatever it is being in my home. Being a grown man, I do NOT scare easily. I'm also not the biggest believer in the other side, extra terrestrials, etc... But the past eight years has proven to me there is something else inside of my home.

The house is at least 80 years old, so I'm sure something bad has happened at some point... But I do not know what. I've talked... Sometimes sternly... When they are bothering me. I've tried some of the things I've read to get rid of them (putting shoes at the foot of my bed facing opposite directions). So far nothing is working. Last night/this morning I was awake the entire night. Ended up going downstairs at 5am to sleep on my mother's couch who by the way no longer has any dealings with them aside from hearing footsteps upstairs.

I have rearranged rooms the past six months, but my bedroom (where most of this is happening) was always in use before. I do not know what has upset them. It has even gotten to the point where it doesn't even matter if I keep the lights or my TV on, still the same knock...pause...knock knock. And the time they banged loudly on my bedroom door... It was wide open, and only about 5 or 6 feet from where I was laying. No heating/air conditioning vent running to move the door. Windows closed. No pets upstairs. It really freaked me out... And it was LOUD!

Suggestions?

Would prefer to get rid of them before it gets worse.
