Literal and important
Receiving a message – by whatever means – in dreams signifies communication, probably from the higher self. Sending a message from a spiritual perspective suggests trying to make contact with spirit.
Psychological / emotional perspective: Dreams themselves were, and still are, considered to be messages from the gods or spiritual realms. As such, they require careful interpretation; images of letters, parcels, emails and other technology can all signify messages from the unconscious or instinctive realms.

To remember the input suggests the information is useful, to forget, that we have the information but must rediscover it.
