Dream About A Sick Foal

So I had a dream that I owned a Foal that I kept in my garden. Me and my partner went on holiday and came back to find out it was poorly and had broke its leg. I got my vet out to put the little pony to sleep. I got my mums partner to take the kids to the park out the way while the vet did what he needed to. I woke up grumbling to myself that my garden isn't right place to bury a Foal and that I don't have funds for another horse so why was I dreaming of another. Feeling confused.
