Was Chris Possessed????

Chris actually said to he woke up that morning that something had been implanted, like he just knew it was going to happen and there was nothing he could have done to stop it from happening. Is this POSSIBLE??? As nuts as it sounds he genuinely appeared to not just love but absoutely adore his kids. So was he just faking all of that??? Even if was a bad drug trip, or roid rage, or whatever is it impossible to fathom that something had taken OVER him???
