Unwanted images that keep pushing in are read as the mind testing its own boundaries. Dream books stress that such thoughts are not wishes, only noise the mind is sorting through.
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.
