If you dream of a computer, pay careful attention to the other symbols in your dream.
The computer is saying “put the pieces together to understand the overall meaning.” Also, if you use a computer a lot during your waking life for work or play, your dream could be telling you to get outside more and take a break from the screen.
If you dream of someone hacking into your computer, there is a sense that your privacy is being invaded. You may be overwhelmed and have the feeling that you are at the mercy of another.
