Cath, should we all have a go at analysing your dream? (The following is completely off-topic!)
My theory about dreams is that they are our bodies' attempts at defragging our biological C-drives (our brains) and we (since we arehumans who attempt to impose order on our often random world) proceed to try to make sense of things. That's not to say we can't gain insight via our dreams. (After all we can gain insight, and bits of wisdom from tea leaves and --for those so inclined

-- from goat guts and other things.) My guess would be you were worried about not having enough of something followed by being worried about having too much of the same thing.
Now, someone please tell me about why I keep having a recurring dream about having forgotten my passport when trying to cross the US/Canadian border. (I cross the border fairly frequently and have never even come close to forgetting my passport. I've never even had any trouble at the border. Go figure!)
Somewhat less facetiously, I'd say your having a sweet little puppy named Keats might be a variation on women wanting to "mother" the poet. I'm thinking of Mrs. Reynolds, Maria Dilke and Mrs. Bently (sp?) John & Tom's landlady before Tom's death. All of these women seemed to care about the young John Keats in a maternal sort of way.
