no-one knows what is really "there" when unobserved. fields don't get us out of having to interpret the wave equation (the wave equation is a whole different kind of "waviness", it's not the same thing as the field); and the wave equation only lets us calculate probabilities. so we don't know. but it's true that some things don't behave like particles when we're not looking.
