I always dream that i switch lanes without looking if theres any cars coming?

Question

what could that mean?

Answer 1

They say that a car is supposed to symbolize yourself in dreams and to pay attention to what you are doing while driving or if someone else is driving, etc.  If you are changing lanes without looking it sounds to me like you might be being a bit reckless or aren't taking precautions about something.  Possibly even selfishness, not caring if you hurt someone by not being cautious.

Answer 2

Cars generally represent our journey in life or they can be a symbol of our body.

If your always switching lanes that seems to me that you are always changing your mind about issues without thinking them through.  Obviously you see this as a risk or a serious consequence in your journey.
