I have never experienced any kind of supernatural or paranormal experience before, except this one time...
When I was 21 (I'm 30 now), I lived in my parents house with my 3 brothers. My room was in a kind of basement down stairs. We lived in Melbourne in the suburbs. There is no history or anything special with this house I don't think. No one I know, including family and friends have ever experienced any ghosts or even heard of anyone they knew experiencing anything like the paranormal. This story is real, I swear it.
I was in my room sitting on the side of my bed which was against the wall in a corner of my room. It was about 10:30 pm. The light was dimmed down in my room and I was looking down at my hands while I was rolling a cigarette. I finished and put the cigarette in my mouth and I swear to God, I looked up and saw a greenish face that was blurred, hovering right in front of me about 2 meters away. I jumped right out of my skin, yelled and jumped right to the corner of the wall while on my bed. I stared at the face, with such an intense fear that I have never felt before. I was scared to death. Then the face just vanished. I ran up the stairs and woke my parents up and told them what I had seen. They didn't know what to make of it. I've never seen anything like that since.
The only thing I can think of was my Grandma died about 3 days prior and I remember a few years back when I was on holiday. I was staying at her house and we had a massive fight and she hit me, I stormed out of the house and never went back there. I never really talked to her since and if I did we never talked about the serious emotional fight we had. I'm one of those grand-kids that selfishly hardly ever speaks to their grand-parents. My Mum always told me she felt terrible about what had happened and the fight really affected her. So MAYBE it was my Grandma coming to me for whatever reason, to say sorry or whatever and because I was scared, she just left. WHO KNOWS...
I still live in the house. By myself now and I pay rent to my parents who live elsewhere. I might have been thinking about her and her death at the time but I can't be certain.
I also want to say, that I think about that evening some times and I so wish I had acted differently, instead of crapping my pants with fear. I have always wanted to see a ghost or an alien or whatever. But I had such an intense indescribable fear that I have never experienced before and I feel that's what made the face disappear. It wasn't even threatening at all but it turns out that I'm a bloody chicken. Maybe if I could have prepared myself for it I would have been fine. I hope it happens again someday.
I am in 2 minds as to what it is you had seen that day but I feel that if it was your grandmother she would have given you some other sign, instead of partially manifesting in front of you, it may have been something that was just passing through. Have you experienced anything else paranormal within your home? Thanks for sharing.
