This question has probably been asked by a million people a million times, so I'm sorry if this is a bore.
I have lived in my home since I was born and I am now eighteen. A few years ago I began to experience strange happenings around the house. I would have these 'feelings' as though there was another person inside of my room with me, and I would find things in my room left in places where I didn't leave them. I would also hear strange little knocks around my room as though someone where tapping their knuckles against my furniture, and on a few occasions something would knock on my door and I would look up to see... nothing. There was also one time when something tapped on a table in the study room of my house. It was a strange tune that I can't remember and I copied it on the table, and a few seconds later it repeated its tapping. Needless to say I ran down the hallway screaming my lungs out.
Recently (over the past few months), things have become much more intense. I feel strange vibes in the study room where the weird tapping took place - they are dangerous vibes that make me want to run away, but I only feel them when I am at home alone. In my room I also feel as though there is someone there, but it isn't a dangerous feeling. It is simply the feeling that there is another person there with me. Along with there feelings, the sounds of tapping on my furniture have become more frequent, and I have heard a voice saying 'hey' as though to get my attention, but, as usual, I can't see anyone when I turn around. I have also experienced a strange screaming sound that came through my TV whilst I was on my PLaystation, and I am almost completely certaint that it was not a part of the game.
Along with these strange 'things' happening, my cat sometimes acts strange in my room. Sometimes she watches something that I can't see and she will stare at it for some time before settling down again. Other times she won't come into my room at all. She will stare inside from the doorway and will seem to hesitate, then she will get up and run off down the hallway. There have been about three times when she has been in my room and she has suddenly freaked out and jumped out and ran out of my room, but that hasn't happened for some time.
However, the most frightening happening was about three months ago when I was lying in bed in the morning, oaking up the warmth of my blankets with my radio on. Suddenly I noticed the newscaster on my radio becoming quiter and quieter until it completely faded out, and another voice faded in. It was the voice of a girl and she kept saying "please, please, please," over and over again for about minute until it faded away and the newscaster came back again. Nothing was wrong with the frequency and it was not an old radio. I have never been more afraid in my life.
Please, does anyone know what is going on? Am I being haunted? Or am I just more keen on sensing spirits? No one else in the house seems to notice anything and it seems to be only in my room apart from the study room (but only in there when I am alone). If anyone knows what this is, please help. I'm starting to get really uncomfortable with it.
