A tupilaq is a creature made to carry out a grudge, and in Greenlandic lore it can turn back on its maker. Dream books read it as resentment that harms the one who holds it.
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.
