The Complete Guide to Interpreting Your Dreams

by Stearn Robinson - Tom Corbett
If your dream featured the saliva of a dog, it indicates that you are needlessly concerned regarding the loyalty of a friend or colleague; you can stop worrying.

A dream of the saliva of a horse is a forecast of prosperity, and the saliva of other animals suggests that you will shortly find a way to overcome your present obstacles and/or outwit your opposition.

Otherwise, see Drool or Spit.

The Big Dictionary of Dreams

by Martha Clarke
Saliva has a fairly complicated symbolism, as its interpretation is not simple. Occasionally, it is linked to gossip and insults that you are afraid to receive. But, it also has positive meanings. For example, if you drool on yourself, it means that you have the sufficient resources to resolve a conflict, despite that you lack confidence in yourself.
