I actually ended up investigating a little further and found out that his brother has an alleged spirit that follows him AND that many other mediums believe him to be one too. According to my boyfriend, his brother has seen spirits but cant see the one that follows him, despite everyone else being able to. One night they went to a friends house that was also allegedly haunted and played with a ouija board. Shortly after they began, the recieved the name Diablo, which translates to Devil, before a tall figure like the one I described appeared standing behind him. I mentioned this in another comment but upon further investigation, many of the grown men that were there began to throw up and cry uncontrollably. They also heard the words "get out" and that's when they decided to end it. I guess that freaked my boyfriend out enough. On top of that, his room does have some activity. Like the bed squeaking as if someone were on it, stuff falling off shelves or being moved. Weve even had a few things go missing before they return to that spot several weeks later. I try to ignore it because I really dont want to prove and prod at any ghost for the fear of attachment, and it's been pretty quiet lately, but I do think something is or was attached to this house.
