I was smoking weed with my friends at the park. We see a cop car coming so everyone hides their drugs in their pants or wherever. It's a woman (short and dainty) and a male cop. They start searching our pockets. They find a joint and a little bit of coke in one of my friends shoes. They start arresting us but before that the woman cop pulls out a small pen like device, puts it against my skin and a blue light flashes for a second (like those hair or tattoo removal lasers) leaving a tiny mesh like scar on my skin. I ask her "what was that"? She doesn't respond. I ask her again "what did you do to my arm"? She looks at me and says "don't worry about it" I start screaming "WHAT THE FUCK DID YOU DO TO MY ARM?" I start screaming louder "did you just vaccinate me" and put my hands on her throat and start strangling her. My friends start fighting with the male cop. I put my fingers in her eyes and started pushing really hard. Her eyes start short circuiting and she starts malfunctioning. The cops starts yelling it's standard procedure to vaccinate everyone who's arrested, for the safety of all other's in the jail. I start losing my shit and mercilessly beating him while screaming "WTF DID YOU DO TO MEEEE" and that's when I woke up.

They were cyborg cops and they vaccinated me. I haven't had a nightmare maybe in 5 years. This was the most disturbing thing I've ever dreamt.
