Things happening

Lastnight while I was downstairs myself and the girls were upstairs bathing there were some things happening downstairs around me. I was sitting on computer and heard a door opening, I went to the kitchen to look, only door in direction of sound, come to find it was open and it was locked & latched. Then as Iwas standing in the diningroom it sounded like someone or something was stomping up the basemnet steps. I then went upstairs & told the girls to hurry up and get done with bath because things were going on & I didn't want it happening up there with them. I came back down to find the kitchen sink was turned on a little. With all this, the feeling throughout was not good. Later on that night, after Karen got home, she was upstairs in the bathroom & she yelled for me to tell me that someone or something was trying to open Brit's bedroom door, it was locked. I went up and seen nothing and heard nothing, but again the feeling of not so good was there & it stayed around until I went to bed.
