A telescope brings distant things close, so it is read as focusing on a future goal or a far-off person. It can also point to looking so far ahead that what is near goes unseen.

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.
