Young girl continuously visits my son and news of pregnancy from his gf

As some of you may have seen my other post of the female we seen at the camping site, then began having experiences at home… these experiences have still continued. The footsteps down the hall. My sons gf woke up seeing this woman looking down at my son. She witnessed this once, then my son woke up to her looking at him as well. The 3rd time my son got home from work and thought he saw his gf sleeping on the bed, went into the bathroom, came back the girl was gone. He went to look for his gf and she was walking the dog and hadn’t been in bed.

My wife and I have been announced loudly, you are not welcome here. We have prayed loudly. We have not yet Sage the house but plan to do more research and do so. A few nights ago, my sons girlfriend had found out she was pregnant. It is also a teen pregnancy, and the night before she found out my sons girlfriend was in the shower and she explained it as the feelings of someone tracing their finger tips across her stomach. She said it was super faint and it felt like as if something was crawling on her. The next day she took a test for her own reasons and found out she was pregnant.

This may be a long shot but does anyone think this could be related or a reason for this to be happening or a reason this thing seems interested in my son? Also anymore advice on this situation would be greatly appreciated. Thank you
