Saliva

As a 'wet' substance that comes from the mouth, seeing saliva can symbolize superficial communication when a deeper exchange of feelings might be necessary. To see someone 'spit' can represent unacknowledged anger or the idea that something said has left you with 'a bad taste in your mouth.' Drooling or seeing someone drooling can be a way of exploring feelings of inadequacy or unacknowledged passion.
