What do آپ think?

Okay, yesterday my mom told me that my brother had felt like he was pushed out of bed. We are living at my Uncle's and his wife died in the kichen like eight یا nine months ago. Before that we lived in this old house and all our دوستوں کہا they saw shadows when everyone was asleep. When we first moved into that house my little brother got really scary, he کہا awful things, mostly to our mother. What do آپ think is going on? What should I do?
