In the realm of dreams, encountering a computer can symbolize the influence of technology, information, and the modern aspects of life. It signifies the opening of new opportunities and the embrace of contemporary resources. However, a computer in a dream can also represent a sense of conformity and emotional detachment, highlighting the tendency to go along with the flow and suppress personal opinions and emotions. It may evoke feelings of diminished self-worth.

When you dream of a computer having a mind of its own, it may reflect anxiety about technology and a perceived loss of control. This dream suggests a sense of overwhelm and vulnerability, where you feel at the mercy of external forces.

Conversely, dreaming that a computer has a virus or has crashed can symbolize an area of your life spiraling out of control, paralleling a situation that has abruptly come to an end. If your dream includes a sentient computer virus creating random or peculiar artwork, it may reveal hidden desires or feelings in your subconscious. The artwork might also serve as a reflection of a situation you are ignoring. However, the specific imagery you described, with a little boy smearing X's with his poop on a calendar, suggests past regrets or remorse.
