It sounds as if your sister (or whoever she represents in your dream) is very concerned with how things appear on the surface. The fact that she was cleaning the counter (surface) with a strong product indicates extreme concern for appearances or surface matters. Perhaps there is some area in her life where she is abrasive (harsh) and legalistic about things.

Now, the car represents a person's self and their life journey. For instance, if you are driving your car, it means YOU are the person making decisions for yourself. If you get lost, it means you are confused about what to do next in your life. If someone else is driving, it means someone else, not you, is guiding the direction of your life.

Your sister, however, was not going anywhere. She was worrying about "surface appearances" in some important area of her life. Meanwhile, something vital has been stolen from the INTERIOR of her life (car) and it's loss is a wake up call for you. You really didn't want to get involved in whatever had upset your sister. You wanted ot ignore it and not look too closely at whatever had occurred. However, for your sister's sake, you get involved anyway. You take her hand... show concern... get involved, for her sake.

Her resolve or calm or faith, or SOMETHING has been shaken by some person or event or concept. She doesn't know how to deal with it... how to answer it... and she wants you to verbalize this for her. She wants you to fix it... make it right somehow. You try, but do not feel equipped to do it.

Now, notice.... this whole time, neither of you has ever yet been inside the car or driven at all. So, whatever the important life issue you're upset about, you've never really looked deeply into it. Neither of you are driving. It's your sister's car your sister's issue, and she's not driving. She won't even pick up the phone! You're not trying to control her life.. you're not driving her car.

But you feel compelled to get more involved, for her sake, so you lay down on the hood and windshield of the car. So, you don't REALLY get into the inside of the issue either. You are only dealing with the surface. It seems maybe that is a little further than your sister has gone, as she was concerned with her own appearance and never even really got too close to the car (issue) before. So, now you are laying on the car (kind of thinking about the situation)_and she joins you there.

The BIG problem is, windshield were never meant to be laid upon. They were meant to be looked through. You have to be INSIDE the car to see through the windshield and be able to navigate and make progress in your life. In the same manner of speaking, you and your sister were not ever INSIDE whatever thing/concept/way of life that you are now addressing for the outside. You were never inside... and the surface of the matter is not strong enough to hold the weight of your problems, questions, grief, or whatever. So, the windshield (perspective) shattered. If you have been INSIDE, looking THROUGH the windshield, it would have been a shield for you as well as a place of clear vision from which to navigate your life and choices. But, instead you approached it only from the outside, so it failed you.

In the process, YOU lost something... something to do with your own value and heritage (birthstone), something important to the HEART of you, and something incredibly important to your LIFE (green). You knew you had lost something very important, but you didn't know it's value, but you knew something vital had been lost and you were sad. Your sister realizes the fact that she pulled you in to solve her issues is partly the cause for your vital loss.

Now, you are back at your family home... represents your family where you grew up. Your sister is still wanting you to confront and verbalize issues, take responsibility, face the family, etc. with whatever has been lost. You don't want to deal with this at home, in the context of your family, for some reason. You're sister gets impatient (is she really your sister, or a part of yourself?) and demands answers NOW, and refers to the Islamic fish store as being able to provide better answers than you are producing.

Whatever the Islamic fish store represents or has to offer, perhaps it is because they have taken the matter seriously and were able to communicate clearly, while you had not every really looked deeply enough into the matter that concerned you and your sister (or self) so much, but could not verbalize, report or defend.

Your Mom seems to play an important role here. She doesn't seem to be helping the matter, only spouting anger and being critical. Your Mom may be somehow at the root of your lack of desire to look closer into whatever matter it was that you never examined below the surface. If this issue was important in your family, and you didn't want to discuss it at your family home, I suspect this may be the case. Otherwise, her voice and words would not be so jarring to you. Girl, it makes my skin crawl just THINKING about it. ;- ) I've had some "shrill Mom voice" dreams myself in the past and they were CHILLING!

I'm sorry this is so long. I'm just that kind of girl. Can never just stick to surface matters... always digging deeper. I make people nervous that way... or at least I make "surface" people nervous. I'm kind of thinking you're not such a "surface" person these days yourself.

God bless you!
