Scène de Walkman au restaurant de voyage dans le temps

I'm sitting in a restaurant, time is passing and I'm eating spaghetti, I'm wearing a tracksuit. Then someone comes, puts a Walkman on the table and leaves immediately. I don't see who it was, I look around but there's no one. The Walkman has headphones, I put them on and press play. Suddenly the atmosphere shifts to the 80s, my clothes change. I look around in surprise and walk out of the restaurant, and I see I'm in 1980s New York. Suddenly a big man in a suit appears in front of me, points his finger at me, and everyone around stops, all like zombies, staring at me at the same time. I start running down the street, and behind me the big crowd that was just staring starts chasing me. I run faster down the street and take off the headphones, and then I find myself back where I started, but the Walkman is still on the table.
