As much as people take it for granted and as much as they seem to forget how bad it can really get, driving asleep is always an extremely unsafe activity. Dreaming about driving asleep means that you need to look into your actions a little more carefully and be a bit more contemplative about your decisions. Don’t make any rash decisions.
If you have a dream where you are driving lost, this means that you probably don’t know quite as much as you thought you did earlier. You think that you know what’s going on and what you should be doing, but really you are having some issues. Do not be afraid to stop and ask for help or to let someone else in on the situation and see if they can give you a beneficial perspective that might set you straight once a more. A dream like this is put there to humble you and remind you that you do not know everything. Sometimes it is best to let other people have a go and sit back while they guide you to the appropriate place. This is just the way life is supposed to work sometimes, as disheartening as it may seem.
