I have experienced a ghost before... or something anyway. I have a large interest in paranormal stuff btw.
... I came back from a late night celebration of partying back then. My sister was working her bartender night shift and my parents were out on a bi-weekly trip to Sweden. Anyway, I remember I wasn't too drunk back then. At least sober enough to know what was happening around me.
After fiddling with the keys and getting through the door, I feel like I could just throw myself onto the bed. I was exhausted. So Im lying there for like half hour or something and can't really get myself to sleep. Twisting and turning to each side. That point I start to hear breathing into my ear, you know like some one inhaleing and exhaleing. That doesn't mess me up too much, I just figured it was my own breathe since everything was quiet.
I just take a look around to confirm my suspision, open one eye. And seriously, holy shit. I saw a figure pass my door way. Like side ways, not walking through it, going towards the kitchen area. From what I can remember it looked like a bride or something, like a woman in wedding dress anyway.
At that point I thought I was probably too drunk and things are just moving too fast for me. So go out following "it" to my kitchen and well, theres nothing there... but then this really unexplainable cold starts creeping onto me.
Anyway, after that night I slept my 2 remaining days at a buddy. Didn't really explain my sister why.
