The sun that never sets is read as a time without rest, when everything stays visible and nothing can hide in the dark. It can feel like joy that does not end or wakefulness that cannot switch off.

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.
