The porch is the threshold of welcome, read as the space where you meet others before letting them in. Waiting on a porch stands for anticipation of a visit or a change.

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.
