Dream About Snake With Cut Off Body

I saw this dream where me and my best friend were getting out of my house and in the garden suddenly we see an enormous snake but I noticed that almost all of his bogy was cut off. It was just his head and a small part of its body just so he could move around. My friends hands me a big gun and i shoot the snake 4 or 5 times (once in the eye) and he seemed completely fine. Then my friend approaches the snake to talk to him as an distraction until we got out of the house and ran while laughing in pure adrenaline
