Can the person who washes the deceased tell others about good or bad signs?

If there are good signs, there is nothing wrong with telling people about them, but if there are bad signs, one should not do that, because this is gheebah (gossip). But if the person says, “Some dead people turn black” etc, that is OK. But he should not say, “I washed So and so and I saw such and such” meaning bad signs, because that will cause grief to his family and upset them, and this is gheebah.
