Hi, stardrifting. Interesting dream.
It isn't as ominous as it might appear. Seeing a brightly lit window with rolling green hills in the scenery is a nice symbol of optimism, wisdom and positive outlook for one's future. The home of the older woman is some aspect of yourself. Could you be peering into your own distant future or what you might think of as being one of many possible scenarios in your future?
The fresh flowers seem to indicate that, generally speaking, this woman's life is positive but the dead daisies and their state...it only reflects how she is "shelving" some memories of past happiness that is no longer. Possibly due to her husband's passing.
