Santa Claus is traditionally read as generosity, wonder and the belief that good things can arrive unexpectedly. Dream books also link him to childhood memories and to being seen as deserving.

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.
