Three Knocks And A Shadow Man

I guess I'll start by saying that I'm currently eighteen years old and I no longer live in the house I experienced things in. The first experience that I ever had was when I was about six years old, in a brand new house my parents just had built. I had just gotten my own bedroom after having shared one with my sister, as you can imagine the six year old me was extremely excited. My room was next to my sisters and across of my parents bedroom and I always slept with my door open.

For the first few months everything was ordinary and then I started having trouble sleeping. I would experience vivid nightmares about walking through hallways where disembodied hands would reach out for me, trying to grab me. Shortly after that I began to hear three knocks on my wall every night, like someone wanted to come in. As a kid, this terrified the living Hell out of me. I went to my parents every night about it and every night they said I was imagining things and proceed to get angry with me for waking them up.

Eventually I gave up on telling them and would sneak into my sister's room to sleep next to her. Every night that I slept in my sister's room nothing would happen. My parents found out and of course, made me sleep in my own bedroom. The knocking started again, sometimes before I had even fallen asleep and sometimes it would wake me up.

One day, after a huge fight with my sister about her taking my toys from my bedroom, I put a sign on my door that said "Keep Out! Big Sisters Only." or something to that affect. Later that night, I heard the knocking as usual - this was one of the times I had yet to fall asleep - but this time I saw an arm reach around and pull the note down. You can imagine the terror I felt at that point, but I thought it might have been my dad (it was a man's arm), so I got up to investigate. I could hear both my parents sleeping in their bedroom and my sister was fast asleep in her own room (which I stayed in for the rest of the night, too afraid to return to my own.). After that, I don't remember much happening. The knocking had stopped for a while.

A few years later, when I had finally felt safe enough to sleep in my room without fear, stranger things began to happen, and I honestly think I would have taken the knocking over what began to happen. I would hear my name being called in the middle of the night and I started seeing a shadow figure stand in my doorway, never entering and always leaving shortly after he appeared. Looking at him, I was absolutely terrified. Thinking about it now still gives me the creeps.

Then, in the last months we were leaving at the house, I had the scariest - and probably strangest - experience I believe I've ever had. Through my bedroom window I saw a silvery light, at first I believed it was the neighbors light on, on their side yard, but then a ball of the same glowing light floated through my window and into my room. It was beautiful, but the feelings it gave me were worse than I had felt even looking at the shadow man. This happened when I was about twelve.

Recently I found out that my sister had had an experience of her own, though it was so different than mine. She would see the figure of a girl sitting on her bed playing with her favorite stuffed animal. The girl had actually spoken to her saying "Will you play with me? Come play with me." But the way my sister talks about is as if it's a positive experience, or like it's an old friend.

My friend drove by that house a few weeks ago (she was curious about it after I had told her all this), and she told me that she had gotten a really negative feeling just going past it.

Soo, I guess that's really all I can say for now. I have had a few other experiences in my life, though not connected to this house in particular. My question is... Why would this be happening in a brand new house? Why was what my sister experienced so vastly different from what I did? I don't know as much about the paranormal as I'd, admittedly, like to.

If it matters, I am Christian but I am totally open to hearing whatever it is you'd like to tell me.
