I wonder what it means that I'm dreaming of her.
Well, she’s clearly a symbol for Margaret Thatcher, and hence for the sort of brutal kleptocratic (deeply and systematically skewed) “free” market that Thatcher represented, and thus also for the current US administration. Therefore, clearly, you must be dreaming about her because you’re worried about your water bill.
[Mind, I have no idea who you’re talking about.]
Since I have no idea who the "her" is, or any context of a situation, I would say it means that you have "her" on your mind. However, with more details, we could be more helpful, unless vagueness is your desire.
