Disturbed Nan?

Im only 13, but I've experienced quite a lot already... But for this story we're going back to when I was 12, and it was the first and only time I saw a ghost.

I live in Wales and was at my friend Chloes house. It was about 11am.

Me and my friend Chloe are both interested in ghosts and spirits and these sort of things. And even though being aware their fake, we thought we'd try an online ouija board before trying a real one, to be aware of the things that you have to do.

We asked for its name. It replied 'Nora' and Chloe said to me, 'thats my nans name.'

We asked where she's from. She replied 'Dublin' and Chloe starting to get scared, said my nans from Dublin...'

We asked how old she was when she died. She replied '84' and that's where Chloe asked me to turn it off as this was also her nans death age.

But I carried on, and asked things that may relate to the few things I knew about her nan. She'd also died in her sleep from old age, and I decided to turn it off as it was all getting a bit too much.

We slept downstairs on the sofas that night. Chloe one end of the room on one sofa, me on the other on the other sofa. We started talking about what had happened, and Chloe was uncomfortable to talk about it.

It was about 1 in the morning. We were on our laptops, when I went to turn around and tell Chloe something, and saw an old woman stood about a meter forward from Chloe's feet. She was pale, average height, dressed in a long sleeved, long dark dress. Her hands were slightly from her side and her face plain. I straight away, very shaken up looked at my laptop, but I had this feeling like someone was watching me, so I turned the laptop off and faced towards the back of the sofa and cried myself to sleep, thinking could have we disturbed Chloe's nan?

Morning came, I was awake before Chloe. Her Mum came downstairs and came and sat on Chloe's sofa, and Chloe woke up. Her Mum took one look at me, while I was still shaken up and had mascara lines down my face. She asked me if I wanted to tell her what happened and I replied no. She asked me if I wanted to tell her in private and I said yes.

We went upstairs and I told her what had happened. She said to me she'd had noises and orbs in pictures upstairs but never downstairs. And comforted me and took me home and promised she wouldn't tell Chloe.

About 2 weeks later I went to Chloe's house again. But I didn't want to sleep. Me and Chloe were messing around taking pictures in the mirror in her living room. In the reflection you could see the area I saw the ghost. And in one of the photos there was a dark blur in the area and surrounding me. I started shaking and told Chloe what happened.

Now every time I go to her house, something similar happens, and has happened even when I'm not there. Have we disturbed her nan?
