To see a computer in your dream symbolises technology, information, and modern life. New areas of opportunities are being opened to you. Alternatively, computers represent a lack of individuality and lack of emotions and feelings. Too often, you are just going along with the flow, without voicing your own opinions and views. You may also feel a depreciated sense of superiority.
To dream that your computer has a mind of its own denotes anxiety about technology and loss of control. You are feeling overwhelmed and that you are at the mercy of another.
To dream that a computer has a virus or has crashed suggests that something in your life that is out of control. It may parallel something in your life that has come to a crashing end. If you dream that your computer has a sentient computer virus that would create random or strange artwork, then it depicts your subconscious desires. The artwork may also be a reflection of a situation in your life that you are ignoring. In particular, if the artwork is of a little boy smearing X’s with his poop on a calendar, then it indicates past regrets or remorse.
