Spiritually, an email signifies fast, efficient communication.
Psychological / emotional perspective: As the email – mail by electronic transfer – takes over from the letter in ordinary life, in dreams it becomes both a more immediate source and purveyor of necessary information.
Material aspects: In dreams, a message by email has for most people moved beyond its initial use as communication in business and become, as in waking life, a way of expressing immediate thoughts and ideas.
If we are sending an email in dreams we have information which others may need.
To dream about email, indicates that you need to reach out to people who may not always physically be around. It could also suggest that you have been spending too much time in front of the computer and this has carried over into your dreams.
To dream of reading someone else’s email messages signifies that you are mistrustful of others and you tend to poke your nose into friends’ business. Perhaps you have recently stumbled upon some information that was not meant for your eyes.
