the other day i was thinking about what i would do once i became lucid the next time. i like all the crazy adventures you can get into without any consequences and without any limits like flying or runnin around creating havoc and whatnot. but, i really believe in the importance and almost spiritual effect lucid dreaming can have on a person. so i decided i would ask to meet my dream guide and see what questions about me could be answered, because, although i am me, how much do i really know me…?? and then i started thinking about what questions i would ask. questions like “why am i so shy?” or “why do i do certain things the way i do?” or other questions like that came to mind. but then i started second guessing all of those questions. what if, when i find the answer to the questions im looking for, i dont like the answer. what if it changes everything. what if im not supposed to know those things? does anyone else have these same worries our doubts? or am i all alone on this one?
I don’t think that you’re all alone by any means… i’m sure that lots of people think about these things. Personally i don’t think that you have anything to be worried about. Surely knowing yourself better can only be a good thing? Even if you don’t like what you hear then you have a means with which to change it. If you’re not supposed to know then the chances are your subconscious or dream guides won’t tell you! 
Hope that helps a bit and good luck! 
Many people think their character is what defines, them, and fell compelled to act out coherently to it, even if thinking about later, you knew in advance taht would have been the wrong choice. Still, we simply keep a self-imposed code of conduit that continues to keep us on the same rails.
Knowing yourself doesn’t necessarily mean you have to change yourself: for example, you could be shy because some friends you opened to in childhood betrayed your trust in some way, and you don’t wanna feel that bad anymore. That’s okay, but if you don’t know it, you will act shy regardless, and you could miss the opportunity to befirend someone that would really count in your life later, even if you knew from the start, somewhere inside you, that he/she was really important to you somehow. Instead, if you know the "why"s of your behavior, you are not influenced regardlessy anymore, thus you have now the power to choose: there might be 1 in 10 worth meeting and knowing, but the other 9 could be best kept at a distance, and it’s perfectly normal to be shy and elusive in those situations.
The answer you might get from a dream might and might not change everything, but if it does, it could be for different reasons: either your past behaviour was unreasonable and you’ve seen the errors of it, therefore you will be more than happy to be free from such characterial chains; or, there was more than a good reason to live that way, and thus, you are completely free to keep behaving that way; only now, you can get off the rails if you saw something really worthy on the grass next to them.
I always went by the adage “Knowledge is power”, and more specifically, self-knowledge is the power to control yourself, to make yourself choose the right options.
My very first LD, my SC just told me I wasn’t ready 
But if he’d answered something I didn’t like, I would just consider it. I don’t have to believe it, right away, exactly as he said. The SC’s an estuary for all sorts of waking life junk.
That said, I’ve journaled some painful things that turned out to be true after some reflection: “I’m annoyed because I’m jealous of this person’s naivety”, “I’m being hypocritical”, “I’ve been playing up this tragedy.” – and just getting it down feels like a huge relief. It’s well worth the momentary ego-burn, and a clear self image is the first step to improvement. 
you can encounter scary stuff if you ask questions like that, instead ask “how can i be confident”
but if you aren’t afraid its okay to ask and learn i suppose?
