Weird entity? Friend having presence issues.

Ok so my friend said that EVERY time he enters SP he feels this evil presence enter the room, everytime he tells it to go away he says it gets mad. Its not in his dreams but I want to help him anyway I can, so any suggestions of what it could be.

You said he gets it when he enters SP. So it's obviously an hallucination. He needs to handle it, if he fears it, it'll gets worse everytime he enters in SP.
I think he can do nothing but try to change this ''evil'' to something that doesnt scare him, it's all in his head in the end.

Thanks, Hallucinations were the first thing that I thought it was too, but I didn't know how to help.

Thanks again
