(this episode aired quite recently here in sweden) 
 
I could really relate to Holly, who had been dreaming about fighting evil. When I met my fiancé a few years ago he was also dreaming the same kind of dreams. I knew he had sleepingproblems and nightmares, so I took it upon myself to sit by his side through out the night, almost every night, in case he would wake up and scared and alone. 
Suddenly he started talking to me in his sleep. He talked and I answered. He sounded different than usual, deeper and more serious, calm. He talked to me about drugs, about cutting himself, he said that it was good for him to cut himself and to take drugs and that he would never quit. The strange thing about it was that he spoke of himself as if he spoke of somebody else, he refered to himself as "he" or "William" instead of "I". 
This happened more and more, and he started giving me cluse on where he had hidden his drugs, and where he had cut himself. For example he allways wore a sweatband with a red star on, and once he told me in his sleep: "he's keeping secrets, look for a secret under the red star". I looked inside his bag that also had a big red star on it, then I found little cuts on his wrist under the sweatband. 
 
I comfronted Billy about this and he told me he had had nightmares about himself and about all his bad sides, old bad habbits and bad attitude he had had before he met me, and that his "old self" was trying to "win him back" in his dreams. He was scared to know that I had spoken to him, which he didn't know at all and wasen't part of his dreams. 
 
After this comfrontation the dreams stopped, only to return a few months later. 
This time Billy's "old self" would start to tell me other things, like "Billy doesn't need you, he only needs me", "I'm trying to help Billy, you will only destroy him" and I would ofcause argument against him and tell him he was wrong and to leave Billy alone. At this point I had accepted Billy's "old self" as a different person, independant of Billy, that I could speak to separatly. 
We'd usually argument fiercly back and forth untill he'd shut up. As soon as he stopped talking to me Billy started tossing and turning, crying and screaming and I'd have to wake him up. 
At one point Billy's old self thretened to kill Billy. 
 
Billy also told me he could experience this other side of him when he was awake, like a voice that told him to do bad things such as cut himself or think bad thoughts about other people including me. I knew this other side had a very strong power over Billy even when he was awake and in his sleep he's allways threaten to tell Billy to kill himself. He'd really push me and say "you know I can do it, he lisstens to me more than he lisstens to you". 
 
My "battles" with Billy's other side heatened, as did out argumentation. I refused to give up and when I diden't he'd "attack" Billy and cause him to cry, toss and turn. When he did that I'd hold Billy close and try to get throught o him, tell him to fight and not to give up. 
Billy often told me about a girl in his dreams that would try to protect him (this was me, but in the shape of a girl he used to know, a girl who had killed herself because of him several years ago). 
 
Billy finally won the fight. I got through to him and told him to lissten to me, not to "him". That's when Billy started talking in his sleep again, but this time I could clearly tell it was my Billy because he sounded normal now. He told "himself" to go away and never come back, and repeated that over and over as he tossed and turned as if he were in great pain. 
Then he finally snapped out of it, but proceded to ask "have you come to forgive me" (I didn't know this girl and how would I know if she would have forgiven him?) I told him "maybe I have. I love you, Billy" and then I woke him up. 
 
When he was finally awake he smiled a true smile for the first time in a long while and said "something wonderfull happened tonight" 
 
 
Is this something similar to what Holly experienced or what was really going on with Billy during this period of time!?!
