I wasn't one to believe in the paranormal at all. Since this weird encountering it hasn't left my mind since.
Years ago when I was about eight to ten (I cannot remember), a close friend of my sister's thought her life was that bad (personal reasons) and hanged herself. It took me weeks or month to get over it as she lived in our house (she moved out of her old house). It was a devastating moment for the whole family. I was crying every single night not knowing what do with myself. I cried in school every day, holding back tears and I had to go to some counseling for a short period of time. It was that bad at the young age I was. I'm not a Christian, and I don't have any sort of religion besides an atheist but I do believe in after-life and ghosts.
Anyways, I was in my bedroom with my door open and my sister was in her bedroom. I was sat on the sofa facing the open door when the attic door suddenly flew right open. It was weird as the attic door was wired up and locked until you either wanted to get into the attic or cut the wires free. It was one hundred percent locked. It was so freaky, I couldn't even describe how still I was. This was a couple days after her passing, and days of bawling. I think she was sending a message saying, "It's okay."
This wasn't the only thing that happened. My sister was at work until midnight, me and my brothers were at school, and my dad was at work (not coming home until 9PM and there would be no way of him getting home as he works a long distance away and my mum had the car), my mum needed to go shopping for some supplies for the week. He locked all of the windows and closed them, followed by the doors and left the house. When she got back, however, all the windows and doors inside the house were open. When my mum told me I got really freaked.
That's only SOME of my many experiences with ghosts, but I know I shouldn't be scared.
