Drooling is an important part of dreaming. For most people, it seems to represent a sinful act like foolish behavior or embarrassment. Many dream researchers believe that it also symbolizes a person’s inability to control themselves during crucial moments in life or connects on a spiritual level to puberty or babyhood.
Drooling during dreams is interpreted differently depending on what was seen while the person was awake. It could mean they were seeing objects they were not able to control such as an intense fear of being incompetent or that they have a childish view on the world. Drooling can symbolize a loss of control and a general state of incompetence whether you are conscious or not.
