I am a 38yr old female with 4 kids. This dream happened the first night I stayed at my boyfriend's house about 2 weeks ago. I dreamed I was in that same house in a bedroom looking out the window into the back yard where there were a couple of people who were digging a grave while a few others watched. They buried someone in the grave and filled it up with dirt. I had a very strong and uneasy feeling in that place. I started walking around the house and found a young girl that was kneeling in a corner and crying. I tried to console her saying "Hey, are you OK?" and "do you need some help?" but she didn't respond. I didn't want to but I went to touch her on her back and she turned around really fast and said something to me. I don't remember what she said but she was very angry and I think her face was strange looking.
The night before that I had another bad dream but I can't remember what it was. 
What does this mean??
