I live in a haunted house and sometimes this works as a disadvantage. One night I wanted to sleep early as I had to be at school at 6:00 for a school trip. My bedroom is right under the attic and I could hear the ghost (s) walk around again as usual.
Finally it was quiet and I wanted to sleep when my door started to rattle. I thought it was the wind so I closed my window and my door and went back to sleep. It was quiet for a moment but soon started to rattle again. I was getting really annoyed because I wanted to sleep. Again I checked whether the door was closed well and went back to sleep. It still didn't stop. In my head I thought, "If this is one of you ghosts again, go away!". That moment I heard my door slam with an enormous bang and the fire alarm went on. My parents rushed up the stairs and shouted, "What's going on? Is there fire?!?!" The only thing I could think was "whoops..." These things happen a lot.
I will tell you more about the ghosts. I can't really say how many there are. All I know is that there's one big black one among them. I've seen him on several occasions. Sometimes he's a bit mean. Like this morning I was home alone. I walked past our hallway when I see a big black guy figure walk to the other side. I had a spoon in my hand and, because I was scared for a moment, I pointed it to him. When he was gone I got myself together and walked to the living room. At that point I heard all cabinets in the kitchen open. Even our dog woke up even though he normally sleeps through everything. That wasn't really nice of the big black guy.
But beside that he's actually quiet nice. Normally he just walks away (and, yes, I can hear and see him walk) and has a good energy around him. He's about two meters high and a meter in the width and almost completely black.
This was a small intro to my ghost.
