Help me get to sleep at night?

Before I ask this question, let me just say that this is not a joke, and any smart-aleck answers will be ignored. I think before I elaborate on my problem, I should tell you that I'm a complete video game geek. My brother and I are both absolute video game nuts. We got the new Sonic the Hedgehog video game for the PS3, and we had a blast with it, and since then, we've been looking up videos on the internet pertaining to it. One video we came across was a fanvid where Shadow buys a mansion that is haunted by... wait for it... the Tails Doll. Since then, we've seen videos about the Tails Doll, and I found one the other day with creepy music, and the Tails Doll had this evil look in his eye... even *thinking* about it gives me goosebumps. Long story short, now, I keep getting the feeling when I'm in bed, that the Doll is just waiting for me to go to sleep so that he can kill me. I know what you might be thinking. I'm scared of a character, and of all the video game characters to be scared of, like Sephiroth, Black Doom, or Darth Vader, I am scared of a Doll. I know it's totally pathetic, but it's true. Could you please help me?
