I've Had Super Wrong Things Happen to My Family

My husband and i bought a town house back in septemberof two thousand 17. We've had super weird things happen since. Most of these experiences have happened on our second story. When we first moved in, our son was only two or three years old. He would be playing all day long without any issues. But whenever it started to get dark outside, he wouldn't want to be in his room. A few weeks after my son stopped mentioning the baby, i started hearing scratching noises above my bed in the attic. I'm normally a heavy sleeper, but at least twice a week i would wake up to a faint scratching noise right above me. This persisted for about a month
