Email 
To dream about email suggests that you should extend your communication to people you may not be in close proximity to. This dream may also indicate that you are working on the computer too often and this mentality has transferred to your dreams.
Instant Message
To dream of an instant message may reveal an important detail about your inner self. The instant message could contain advice or a clue to your innermost desires. Alternatively, you may be too heavily occupied with gossip or chatter in your day to day life.
