A virus is an infectious agent so from a spiritual viewpoint is a pollution or corruption of information or knowledge. Dreaming of an infectious virus has the connotation of us having caught a contaminant or had it passed on to us. Our emotions and feelings may be out of sorts. Dreaming of a computer virus suggests that a system of communication has broken down or been contaminated and we should perhaps try a different approach. A health virus suggests something a little more personal and is more concerned with our own reaction to actual physical infection.
