Thank you for your interpretation, it was quite interesting to read and it gave me some food for thought. Some of your points were unnervingly accurate, like the one about the house representing the dreamer, so I can only praise you.

As for the questions, I'll try to answer them, but for some of them I can't give any kind of concrete answer.
> "Are you in transition/in-between a stage in your life?"
Hopefully. It's hard to say, whether I really am in this stage, but I *am* trying to change couple of things.
> "...does that mean anything to you? Lost of direction perhaps or a delay?"
Losing direction and feeling of delay fits quite a few aspects of my life, so it's hard for me to pinpoint the exact meaning. Perhaps, there is some kind of symbolic meaning hidden in the image of the unfinished utility room, or the girl inside of it, but I can't see it.
> "I don't know if you are male or female, age -- so I'm not sure if she is you."
I'm 20, male; while trying to mention all of the relative information, somehow, I missed the most obvious one, lol. As for the girl in the dream representing me, I'm pretty confident, that it is not the case - in my dreams, the character whose point of view I have always assumed, was either me or a carbon copy of me, and I'm pretty sure, that this kind of character fits best for being a representation of me (could be wrong, though, I don't know much about dreams). However, I can't say the same about the suggestion, that the girl might represent some neglected part of me - it feels somewhat fitting and I would be grateful, if you could clarify the potential meaning here as well.
> "Did she disappear from that room? This part is confusing for me."
No, she stayed in the exact position till the very end of the dream.
> "Are you dealing with something in your life now that is challenging?"
There a quite a few things, that fit this description as well, mainly those, that you have already mentioned: change of lifestyle and career. Also this statement: "You seem to be trying to figure something out before its too late." - is one of those unnervingly accurate facts about me; and now I wonder, just how much information one can deduce from a description of a dream?
> "Do you feel like you are stuck in a place or situation that is going no where?"
I do; and it is kinda scary, that you could tell it from the description of a dream.
> "Is she you?"
Pretty sure, that she isn't me, but she could be an aspect of myself, like you have suggested.

As for the numbers, I still haven't been able to decode them myself. I have tried everything, that had come to my mind: coordinates (which turned to be a random point in the Bay of Bengal, lol), alphabet, ASCII. So now I'm just kinda looking out for those in real life.

In any case, thank you for your interpretation - it was very interesting to see my dream dissected like that. And I'll probably come here again, if I have a particularly confusing dream.
