An uncle is read as a guiding male presence at one remove from the father. Tradition links him to protection, humour or a different path from the one taken at home. A favourite uncle in a dream is read as encouragement and a reminder of easier, playful times. A distant or quarrelling uncle is taken as tension with family authority, or with a kind of masculinity you do not want to copy. An uncle giving advice is read as wisdom from an outside point of view. Dreaming of an uncle who has died is taken as remembering his example. The dream may ask what he represents for you, and whether you need some of that now.

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.
