I had a dream that I was having problems with my breaks, it seemed like I couldn't get the car to stop and I remember the anxious feeling... i never hit anything... but it was scary.
Driving a car in your dream represents your path in life. No breaks and being unable to stop most likely means you feel things in your life are changing too quickly. Maybe you'd like for it to slow down to allow yourself to ponder and consider the direction you're headed. I've had a car dream where I was holding onto the roof of the car and it was going so fast. I was clinging on for dear life while it was swerving, seemingly trying to toss me off. A couple times I've had this dream where I'm on an elevated highway and the road goes up like a ramp then it's a drop-off. I end up launching across the gap and landing on the other side. Scary but exhilarating. Oh, I looked that up in a dream dictionary. Brakes not working: might suggest high anxiety or losing control of a situation or events, may indicate a fear of taking chances or initiating things in case they get "out of hand"; alternative definition: difficulty in controlling sexual desire or emotions. Any of that add up?
