The porter is traditionally read as help with the load. Dream books connect it with letting others carry part of your burden, or with carrying what is not yours.
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.
