Paranormal activity

XXII. "My paranormal experience"

"When zZaRagingClueZz was 16 or 17, he had just moved into a new house with his mother and sister. He had the bedroom in the basement. About a month after moving in, he started noticing bizarre things. Hangers would sway as though there was a wind, and he often heard light, unexplainable knocks in the middle of the night. It was creepy enough to make him move all of his belongings to the spare upstairs bedroom.
One day, while he played video games in the basement, a white mist shot out from behind their television, up the wall and across the ceiling. He bolted out from the basement and told his mom, who told him it was just his imagination.
Over the next few months, he started hearing knocks and seeing objects move again. Slowly, it started getting stronger. Then whispers started, then painful screams. Soon, it was happening every night without fail.
One night, he was left alone while his mother was away for business and his sister slept at a friends.. It was 1 am and very little was happening - paranormally speaking. He was about to fall asleep when he heard a loud shriek of his name. He "slept" the rest of the night with the lights on. The next few months passed with only minor incidents, but then things really got crazy.
Late one night, he was watching television in his room when his bed started shaking. At first, it was only a small tremor, so he ignored it. Then, he began feeling something pulling at the covers from the foot of his bed. A cold hand grabbed his ankle, and tried dragging him. He screamed, and his mom and sister came running.
At that point, it was clear something very weird was going on. His mother called the people who sold them the house and told them what happened. The former owners, although offering no reason for the intrusions, had their priest come to bless the house. The occurrences never fully stopped, but they did become much less frequent and intrusive after the blessing."
