Scared To Make Eye Contact

I was about 10 years old, on a family holiday with my two sisters and my dad, my mum and dad are divorced so my dads new girlfriend was with us. We stayed in Spain, in a building divided into 3 flats and a shared pool. The holiday was pretty bad and my little sister had really bad chicken pox.

My sisters and I shared a bedroom, being a boy I had my own bed and my sisters top and tailed in the bed next to me, my older sister was lying at the same end as me, the end with the headboard and my little sister was lying at the other end where there was no headboard, I could see my little sister whilst lying on my side and there was a small table between the two beds which had a lamp and 2 glasses of water on it.

One night I woke up because I was thirsty, it wasn't hot because it was february at the time but I don't remember it being cold or chilly at all. The room was quite well lit by the lamp and the walls were light orange which reflected the light and made the room feel lighter. I was facing the right wall from my bed when I woke up, I then turned to the left to grab my drink from the table between the two beds, my eyesiight was fuzzy because I had only just opened my eyes, as I was drinking my eyes started to regain focus. In the corner of the room by the end of my sisters bed was a white misty figure. It was moving slightly and I recognised who it was immediately, it was my mother's mother. She did not make eye contact with me, she looked busy, like she was picking up my little sisters pillow off the floor and then stroking her head, I think its because my little sister was ill and she was doing the grandmother thing. She was a very Hazy figure with mist floating around her, like a human standing in fog but not in a scary way, it was more peaceful and soothing. I only saw this for about a second or two because I was so scared of making eye contact with the ghost. I slowly creeped back around to the right and shivered myself back to sleep, all of a sudden it was cold and I was paralysed with fear. When I got back from Spain I told my mum and she completely believed me but nobody else did. My mum is a believer in everything paranormal and has some wierd phsycic abilities, I can't really talk about them much though because I don't really know what shes talking about haha.

What I don't understand is why I was so terrified and why she was in Spain!? I only ever met my nan a few times when I was young because she died of cancer however I knew it was her, I even recognised the pyjamas she was wearing, my mum kept them after she died. I wish she'd come back and this time I won't be scared.

This was NOT a dream and I have never had any other paranormal experiences since.
