I keep dreaming about driving along a motorway at night and seeing a car driving towards me, so I try to change lanes but being unable to, I don't seem to panic in my dream but then the car gets about 2m in front of me and I wake up, I'm sitting bolt upright in my bed sweating, every single time. I have dreamt this 3 times in one night and then once the previous night, can anyone tell me what it means?
