One night, my mom was sleeping on the couch and woke up to find our light-up ball. She fell back to sleep, eventually. She awoke to find the ball there once again. She then threw the ball out of the back door. The next thing she awoke to was finding that light in my sister's bed.
On another night, my sister was grabbing clothes out of her closet. As this happened, she noticed movement behind her. She instantly thought it was me. When she turned around, she screamed as it was a little girl she had never seen. As we were in the living room, we heard her scream. She then told us her story.
Once, as we were searching for pictures we heard a loud bark. Our dogs were in the living room so we figured it was them, but it sounded a little different and louder this time. Right away, we raced into the living room to find our dogs sound asleep. They would've never been able to fall asleep, after barking that much, right away. Therefore it was not our dogs, but who was it?
Another time, we wanted to make our own haunted house. We used each other to try to scare our sister and her friends. When we were leading them into the kitchen, we heard rattling inside the utensil drawer. We also saw the drawer open and the utensils moving. Keep in mind, all of our lights were out except one very small flickering light, only enough light to see to walk. This was a perfect time for a ghost to act.
One day we were playing in our backyard, as usual. Then we climbed into our tree house and found something unusual. We found a knife (which may be the reason for the past story told.) We did nothing with the knife, but it has shown up from time to time in different places. We are not sure why the ghost would want anything to do with it, but this is our conclusion.
