If this rock guy is a reflection of some inner state, like some are saying, what does that say about your inner state? Say he is a soulmate. And the reason he showed up as an unavailable has meaning. What does that mean about your inner state?
Why would a soulmate show up but not be reachable? What is the hidden message that could be there? He could be showing up like this just to help you see how you get attached to individual objects of affection and put them on pedestals. I know you think you know him. All you know is you think you would like him.
I know you say you know some specifics about him and you have these "signs". So why the signs? To show you something about yourself. To help you realize what you are doing with your thoughts and attractions and where you are placing your energy. This thread is choke full of that kind of energy. I mean that kind of energy that is latched onto some idea or thoughts about the way it should be for you. It's all to show you how you are able to fall in love with someone you haven't even talked to, how powerful your mind of thoughts is, how imagination can produce signs.
The signs could also be without you - that having something about this rock guy show up is the universe poking fun at you saying - "here's your soulmate but all he's here to do is show you how you latch on to your thoughts about soulmates and signs". I not kidding. Signs are this way too. They are messages that kind of play with you to help you see how you are operating - and even tempt you into exercising your ways. The universe will say "Hey, she would like this guy so let's tempt her into her pattern of falling for an unavailable guy so her imagination can get going on this - let's send her some 'signs' that he is the one". Then once you see a sign you get to feed all this in your thoughts which of coarse the universe will pick up on and generate more of the same.
It might be a chicken and egg issue, but usually it comes from the inner self, with a bit of imagining - and then a "sign" and then imagination gets tipped off into gear and then more signs -etc... Even then signs that seem unrelated to your conscious thoughts - are really just subconscious manifestations that pop out in the universe for you to more easily see what your subconscious thinks it wants.
It's to hopefully bring awareness to what it is you are doing that isn't working or to expose your ego's unconscious desires so you get a chance to not set yourself up for disappointments.
