What does Buddhism say about having dreams about the Buddha?

Is there any meaning given to dreams of the Buddha? For example is it considered an omen a sign or meaningless ...? EDIT: Sorry i have to change the edit back to the Buddha instead of Bodhisattva.My question is about someone dreaming of The Buddha.As in **Buddha,the fully enlightened** being.Not a Bodhisattva.Not a dream about Sidhattha.But a dream of the Buddha. My question is,Is there any meaning given to dreams of the Buddha in Buddhism.For example if you dreamt of The Buddha would it be considered an omen,a sign or meaningless. Thank you
