What does it mean when I dream of live worms attached on every part of my body?

This dream suggests withdrawal from some addictive substance; the sensation of bugs, ants or worms crawling over or beneath one's skin is a common symptom of withdrawal. (see attached link below.)

Another possibility is that the worms are a symbol representing some sort of disease or uncleanness. In that case, the dream is alerting the dreamer about a very bad influence. For example, a new group of friends might not be as harmless as they seem to be.
