Help With My Recent Lucid

I had a lucid dream last night and it started out as a nightmare. I was being attacked by some sort of demon/warewolf and thats how I became lucid. ive been wanting to ask what my most common dreamsign, water in the form of rain, rivers, oceans, lakes, or ponds, represented. I found my sister and took her into a bathroom where a bathtub filled with water was. There were some old water stains on the tub and I asked my sister "what does the water represent?" She said "It represents happiness with your community" I asked what about the other water (meaning lakes, etc) she said all water is the same except for half and half water which I didnt know what she meant.

She slowly turned into my GFs daughter and i told my self to wake up which I did to a false awakening.

My question what does the whole happiness with my community mean? What community is she talking about? Should i try again and just ask in front of an actual lake or ocean or river? My dream wasnt high lucidity, just to point out
