I had a dream last night that I was going to get mugged by these guys on a bike, so I decided to pretend to ring the police (idk why I didn't actually call them

). So I'm walking along shouting police please there's people following me and I think they're going to attack me, I'm at blah blah blah.
They end up peddling towards me and cornered me into what seemed like the edge of a cliff (idk at first I was walking through blocks of flats) and I'm shouting "IVE JUST CALLED THE POLICE THEYLL BE HERE ANY MINUTE" and then this one guy grabs hold of me and holds me towards the edge and is asking for my stuff I have on me.
I'm trying to fight him off by fidgeting and then he puts me on the ground and something happens then we're both on the ground and then people from the TV show Casualty shows up and ends up rescuing me.
I have no idea what that dream was about.
