I don't dream about my pets who are gone...I do something that is probably very silly, though. When I am looking for a new pet I always ask my beloved pets who have gone on to help me make a wise choice for both myself and the new pet. Because, really, who knows me better in terms of pets than my former dogs and cats? I especially ask my old cat Boo, who lived with me for 17 years and was terribly fond of, well, just about everyone, be they human, canine, or feline. Anyway, even if it is silly, I think it doesn't hurt anything and it is respectful of the relationship I had with pets who can't be with me anymore right now.
