If you dream of going on Facebook (or about a Facebook page that you do or don’t have in real life), it symbolizes that you need to reach out to people who may not always physically be around. This dream might also suggest that you are spending too much time on the computer in your waking life. Maybe it’s time to get outside more and take a break from the screen! If you dreamed of leaving a message on someone else’s Facebook , you may be put into an unpleasant situation.
If you dream of getting a new message on your Facebook , there will be a change in your affairs.
To dream of reading messages on - or hacking into - someone else’s Facebook page 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.... My Dream Interpretation
