Quicklime reacts fiercely with water and was used in old building and burials. Dream books read it as intense reaction, and as the wish to cover over or dissolve something completely.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
