Had a weird dream last night…

I was being chased by a helicopter with guns (Dreamcatcher).   I was trying to get away from the copter and headed into the woods.   Then there was snow or white sand on the ground.   I came up to what looked like a river that was divided by something like a sandbar but it was very white like snow or ice on the ground.   I did not feel particularly cold.   I kept going until I ran up on a group of people talking.   When I looked to the right I noticed a chain-link fence, like a cage high off the ground.   I don’t know where I was I don’t recall anything like this here or where I’ve been.  I ducked down…
