Ok, not sure where to begin. It started 5 nights ago when I was lying in my bed. And at 23:03, I heard a voice say "Who is it?" followed by a knocked on the wall that connects my room to my sisters. Then the next day(the 10th of November), I was walking upstairs and on the 8th step the atmosphere completely changed. It was freezing. No windows were open.
Then, that night, I was in my bed and it was 23:03, and I heard the same voice say the same words "Who is it?", this time follow by 3 knocks. I felt like I was being watched, but couldn't see into the dark corners of my room because my eyes had not adjusted to the darkness, as I had been on my mobile phone up until I heard the voice.
I've looked at signs of haunting and I've identify about five signs, ( Unexplained noises, Items disappearing and reappearing , Feelings of being watched, Unexplained shadows, Cries and whispers).
I didn't stay in my room that next night. What's happening?

What does that have to do with your sister?

If this just started the other night... can you think of a reason something might be in your home now? Were you playing with a ouija board and playing with any kind of spiritualism?

Have you talked to your sister or parents about these noises and voices?

Let me rephrase... you said it seems to be on the wall connecting your room with your sisters... has she mentioned anything about something going on?

First of all thanks for the response. Have you ever read a book called "the Magic"? At first I thought it might have something to do with it. But I'm not sure what is happening. Even as I write this I can feel a presence, something watching me. I've talked to my Parents and they chalked it up as "Too many horror films". My sister hasn't said anything to us, but I did reconise her voice.

You recognized her voice? Explain what you meant by that, if you do not mind.

I can't say I have heard of a book called "The Magic". Is it fiction or non-fiction? Do you think there is the possibility of your sister dabbling in the occult?

The best way might be to ask your sister if anything is going on... is that something that would be uncomfortable for you?
