I'm Haunted?

I've always loved the paranormal, even at a very young age. I remember my mother telling me that when I could barely talk I would have conversations with something she could not see.

One of the earliest stories my mother told me was when I was about six and my younger sister about three. She put us in the bath and went to check on my nephew, when she saw a little girl run from the bathroom to my bedroom. Of course she thought it was me and she quickly went to check on my sister who she thought was all by herself but when she reached the bathroom both my sister and I were in the bath.

Many years passed before another memorable event happened and that was last year. I am now fifteen years old and I quickly try to logically explain these experiences. My father was in Alaska for work so it was just my mother, sister and I plus our two dogs. We all fell asleep in my parents' room and around two I woke up and felt really thirsty. So like any other night I got out of bed and headed to my kitchen. I began to feel watched but I just told myself it was nothing.

It wasn't until my way back to the room when I heard two little girls laughing. This terrified me because both my mother and sister where sleeping and the televisions were all off. I quickly ran to my mother's bedroom. I didn't tell anyone what happened that night.

A few months passed until my father came back. That next morning my father told me he saw two little girls standing in his doorway but only saw them in the reflection of the television. He changed his story once I told my sister and reassured her it was only a dream he had. I told him my story and he didn't believe me.

Nothing seemed to happen until my friend and I started to hear banging on my walls slowly making it's way to the corner right beside my bed. We called it out telling it to show itself. We hid under the blankets for awhile before revealing our faces but when we did, right above me there was a face, bright and slightly glowing. I didn't really want to believe it but after what happened I couldn't.

I was later told his name was John and I reminded him of his daughter. I don't really believe it since I only saw him once. Nothing seemed to happen for a long time until today. The same friend and I were in my room when we heard banging and talking. We thought it was my sister and her friend but when I asked her she said they were in the living room watching a movie. I began to see things. First what I thought was a head and then an hour or so later something completely covered my friend's arm out of my view but both times only for a second. Keep in mind this friend and I hang out multiple times every week. I'm not sure what to call this.

Am I haunted or is the house? Do I have a gift or is it just coincidence? Will things get worse?
