You already answer your own question. It's not about the dream
that makes you think this way. It's not because you think of her so
much that you dream of it. Go think about this, why do you want to
know if it's because you think of her too much that you dream about
her.
If it's never in your own thoughts, it'll never occur to you to
think that the dreamt meant anything.
Like Feow said, it's just a dream. But it's not a dream anymore if
you have to ask this kind of question. I dream everyday. For years,
I dream of tall buildings. I dream of alot of things, does that
mean anything? I dont' even bother to find out if it meant anything
unless I want it to mean something. Is that what you are seeking
for?
Now you know the answers to your own question?
