It all started when my friend and I made our own Ouija board - and it worked! I was always curious about using one as I did not think it would work.

That night my two friends and I were asleep, but I was awakened by the feeling of something brush against my feet. I burst into tears straight away as it terrified me. The next night I slept at my own house and my boyfriend was asleep next door. Half asleep, I heard my bedroom door open and the sound of something running up the stairs into my bedroom. It felt like someone was standing in the center of my room staring at me.

There was a kind of black mass in the air, which is quite hard to explain. I called my boyfriend repeatedly and banged on the wall several times to wake him up, but he didn't. From that moment, I do not remember what happened to me, but my boyfriend tells me he found me lying on his bedroom floor crying. Then he says that the muscles in my body were having a spasm of some sort, like I was having a fit.

After around five minutes of this, it all stopped and I was normal, not remembering what had happened. I told my parents, but they said I was being silly. I changed rooms after that day, and it felt like a weight had been lifted. A few nights later, however, I heard knocking at my door, like someone trying to get in. It also touched my cheek when I was lying down.

When I went into my previous room the other day to collect some of my clothes, my lamp was thrown at me from the desk. I was so scared that I ran out straight away. Whatever this is, it is driving me crazy as I am only 16 and I am not getting any sleep. Do I have a ghost? And why is it trying to hurt me? - Natalie W.
