Something Bad In My House?

Before you start reading this I suggest you read my previous story "Ghosts in my home", but you don't have to read it to understand the stuff in this story.

Okay, so, these past few months I've begun to suspect that there is something bad in my house. Not necessarily something evil, but definitely not something good. It started about six months ago. I noticed that every time I came home, I immediately felt this wave of anger come over me as soon as I walked through the door. I've noticed several times in my life that I tend to "take over" the feelings of spirits/ghosts around me. Their emotions become mine, and I literally feel like I'm feeling someone else's pain/anger/sorrow/frustration or even happiness.

So, anyway, the anger thing was the first sign. Soon after that started, I began feeling these cold spots around me, usually when I'm alone in my room. The cold spots are almost always attached to my hands, and when I move my hands away from the cold spots, it will only take a few seconds before they find my hands again.

Also, the blowing in my ear (which I talked about in the other story) has increased, not only in frequency, but in strength. And now it can even happen when I'm in school, or at a friends' place.

A few weeks ago, when my sister was staying over for the weekend, I was in the living room getting some pillows and blankets for my sister. It was in the middle of the night, and everyone else was asleep, and my sister was in the bathroom getting ready for bed.

When I turned back to the hallway to go back to my room, I saw a girl standing outside my bedroom door. She looked at me for a second, and then walked into my room. At first I thought it was my sister, but then I realized that it looked nothing like her. Plus, I could see the light from the bathroom. I stood frozen on the spot for a few seconds, and then I slowly started walking towards my room, and when I got there the girl was gone. I was so freaked out, so I just stood there frozen until my sister returned. We didn't get much sleep that night.

A couple nights after that, I was sitting in the living room with my brother. It was around 2am and everyone else had gone to bed, and my brother left to go to the kitchen. And a few seconds after he left, I started feeling really cold, so I moved to the other end of the sofa (closer to the heater) and the cold disappeared for about two seconds, and then it was all over me again, along with some weird, disgusting smell. I felt really creeped out and left the room quickly, and the cold spot/smell didn't follow me this time.

Also, a few nights ago when my dad was the only one awake, and he was on his way to the bedroom, he heard this extremely loud bang on the desk right next to him. It was so loud that he could feel the vibrations on the floor, and he thought the whole family was going to wake up. But no one woke up.

We had a séance in my house about four months ago (my stepmother is a medium, and my brother is a sensitive, or whatever you call it) and I found out that I had a spirit attached to me. It was a fifteen year old girl who had committed suicide. She had apparently had a very shiatty life, living at orphanages and foster homes. And my stepmother told me that this girl's name was Laura, and that she was very fond of me, and that she had been lying next to me in my bed at night trying to talk to me, and that she had followed me everywhere. I think she was the reason I felt so sad all the time. And even though I couldn't see her, I think I could hear her sometimes at night. Because, every time I went to bed, and started falling asleep, I could hear someone talking in my head, and even though I couldn't make out the words, I always found myself responding with a "yes", "no" or a laugh, and that would always wake me up completely.

Anyway, at the séance, my stepmother told Laura to move on and let me go. But Laura didn't want to leave me. It took a while, but eventually she went into the light. And after that, I stopped feeling sad, and I stopped hearing the talking in my head at night.

And then came all this negative stuff that I think is here now. And I've started hearing a voice in my head every night, again. Mostly it's just mumbling, sometimes it's just someone saying my name, and sometimes it's someone clearing their throat loudly.

I think this spirit/ghost/whatever is, has started to affect my dad as well. Because he's not acting like himself anymore. He's always angry and picking fights with everyone for no reason. And I can tell that my stepmother is really worried about this.

Anyone have an idea as to what this can be? Does it seem harmless, or is it something really bad?

Sorry for making this so long. I hope I didn't bore you.
