To see a computer monitor in your dream refers to your thought process and rational thinking. If the monitor flickers or blacks out, then it suggests that you are looking at a problem all wrong. You need to re-evaluate the issue. Alternatively, the dream may be a pun on your need to “monitor” or keep track of a situation issue or problem.
To see a monitor lizard in your dream represents change and agility. It also indicates your objectivity in a situation.
