About 7 years ago my brother and his wife moved into a house and believed it was haunted by the person that lived and died there before they moved in, this seemed likely because when they called his name and asked him to stop what he was doing he would. However about 2 years ago he "played" with a ouija board with some of his friends, the first time some things happened that scared him so he stopped playing and went home, but he doesn't learn that quick, he actually went back a few weeks later and played again. This time when he "played" and went home things were very "loud" and they would see a dark shadowy figure the trick they were using before was not working and one night the covers were pulled off and my sister-in-law said she heard a growling noise next to her ear. Now they are divorced and he is living with his new girlfriend and she has small children who have seen this dark shadowy figure and they said it scares them. I don't believe in ghosts only angels and , but what is this and should I be concerned for my brother and his new family? I am worried and would like any help on this issue.
