I don't think I'd have liked being named Dream. Dreams are by nature ephemeral and when they 'come true' they usually aren't a bit like what one expected. OK, the same applies to babies! But if there must be word names, I'd like them to be more solid and three-dimensional.
I also find the current fashion for saying "Follow your dream - if you want to be/do/get something, then you will" actually counterproductive. It isn't true that someone who is barely capable of finishing high school can become a marine biologist. It isn't true that spending five hours a day in the pool will get a relatively untalented person into the Olympic swimming squad. And it isn't fair to deceive them, because in a contest between dream and reality, reality wins every time.
