Come on, let's go for great nightlife adventures

It is night, I’m an undercover cop in a white van which looks like an ambulance. My colleague is behind me. We park the vehicles near a bus stop. We get out of our vehicles. Every time a car pass us I run after to make them scare. I get in my colleague car and he takes the van. We go in different direction. I’m driving when suddenly I realize it’s a dream, my body start to float in the car. The car starts to levitate in the air at the level of the roof of the houses and I start to accelerate, while driving I ask the dream a personal question but no answer. When I stop I’m now on the edge of a very high purple mountain and in front of it there is a tunnel hangs in the air which is transparent. My friend joins me with his vehicle on the edge. So we go in the tunnel at a very high speed…
