A Lucid Dream

Weird dream today. Mom wanted me to renew passport and mine was left in cabrio but was driving Octy. While driving home route was semi-familiar but full of industrial obstacles; gas pipelines and viaducts being constructed.  Also, road was full of morons running red lights and light trucks racing me. Car felt very sluggish and on one instance forgot to release parking brakes. Very stressful dream which led to me waking up with palpitations. Realized also that I do dream in living colour. What kind of time constraint and rat race am I supposedly feeling the pressure from to have a dream such as this?
