Is it normal that i kill people in my head

This happened to me for years. Then I found out I have OCD, and according to my doctor, I was actually instinctively thinking this stuff as a way to cope with it.
Go to a doctor and ask to be checked for OCD, it will save you from a lot of confusion.

Just KNOWING helped me. And even if you don't think you have it, you just might.
Trust me, I went through this. EXACTLY this. I thought the same thing about it too.
These thoughts don't make you a bad person!

The truth is we're all Mad here.

I'm just going to assume that you sometimes imagine your a samurai in a heavy fought battle ready to give it one final go before you fall to the floor. As you pant you look into your enemies eyes and feel a euphoric feeling of intimacy, but in the eyes of death, for your challenger and yourself have allowed each other a worthy opposition. A battle, true test of strength for two great warriors. As you look into each other's eyes you are both counting down to the final strike. You know each other so well from this fight, which was almost as beautiful as a ballet, but much more brute. The swings of iron make dashes like the sound of a bow on a violin. The chattering feet sound like the beat of a drum. The heavy breathing, almost like the sound of brass in the opening gates of heaven. And as the two of you had danced, a beautiful symphony had evolved. Beautiful like a fresh rose, the color of blood that run down your sword. A flashback to the day the two of you were young. Watching koi fish in a tank swimming around, fighting but almost like a dance, ...almost like the battle you two were having right then. Blue and red, elegantly dancing but never mixing because purple is the equalizer and blue and red are brothers. And to mix them would destroy something beautiful. And as your grandmother called the two of you for dinner, childishly, the two of you raced home. "Hungry, you children must be. So much energy comes from childhood. Energy which drives competition. An energy that never dies. In a way, we never truly grow up" that energy lasted to this day. Innocence was lost long before, but the competition stayed. Final it was time to strike. And the two of you dash. Passing each other a delayed strike was heard, and everything turned black and white. As now you see your former friend smirk, but his eyes are obscured by shadows. He falls after a minute long pause after literally getting sliced in half by a fucking sword (drama moves at its own speed k?) and then you see yourself. With your dark blue hair obscuring your eyes. A red blood drop comes down from where your eye should be. These are not tears, but a mans response of the cruel world creating a situation where you had to kill your once best friend. But life is funny that way, we all are victims of different paths, in the end, one must end another, but destiny being fulfilled brings happiness after an apparent sorrow. Your eyes never meet again, because you were once looking at your past and now your looking toward your future, a future without a friend. You go to his funeral, because after death, we remember the good times and not the bad times. You look up and see a blurry vision of your friend, and as you look at him he smiles and nods at you, congratulating you on your victor. And as you look him in the eyes you whisper...Get Fucking Good Scrub. #420blazeit
Anyway, you watch too much anime. Which is fine, just don't be a weeabo and realize that it's fucking cartoons. I fucking love sponge bob, I do not fantasize about being a sponge.

Because you're slipping abit. It happens, but is easy to pull out of if you're aware of it. If you have real trouble YOU WILL KNOW and should see a doctor.

You've got ishes in your shoes. Although I can relate to feeling like someone is inside me, and I don't even mean that sexually.
