The cruise ship is read as comfort carried across deep water — pleasure, rest and a crowd, all kept afloat by something you do not steer. Dream books link it to a wish for an easy passage, or to drifting along with what everyone else is doing.
Where in your waking life have you met something like this lately?
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.
