Plastic wrap keeps things fresh but also shuts them in, so it is read as preservation and isolation at once. Being wrapped in it in a dream often points to feeling smothered or kept at a distance.
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.
