Someone Trying To Contact Me?

Location:Australia

First of all I will start off by saying, I am 100% true to these experiences, and what I'm about to tell you is the absolute truth of what I have experienced in the last few months. We live in a house that was built over 30 years ago, but nothing strange has happened to it prior to that time. One night, (this was in May) I missed my brother who was away for a month for work. So I went and slept in his bed. At about 2-3 o'clock in the morning, I open my eyes. The computer chair, which was supposed to be on the other side of the room, was right there in front of me, and as soon as I noticed it was there, it turned and faced me straight away. But nobody was sitting in it. I was scared, and fell back to sleep by hiding my face under the covers. In the morning, the chair was in it's original place. Another one, I went and lived with my grandparents in July [due to complications with the family], and I slept in my grandmother's bed while she was downstairs. The lights were on. My grandmother's bed is right next to the door, so the hallway lights would appear in her room. I open my eyes, and upside down, there's this face that is looking down on me. I saw it, it had a nose, eyes, lips, it was a face! And I was concentrating on it more and more, it disappeared. It wasn't my grandmother.
This one happened two weeks ago. I was in my room, listening to music on a late night, and I heard my brother call out my name. "Shannon!' it yelled. I turned down the music, looked at my door, and said 'James?' But no reply. So I went over and I thought James was playing a prank, yes, I was THAT positive that I heard something or someone call my name. But no one was there. So I went back in my room, closed the door and got back to what I was doing. Half an hour later, he says it again 'Shannon!' and this time I KNOW something is up. But he wasn't there. Nobody was there. Could I be hearing things? No. I know what I heard! What do you guys think?
