(See Sound of animals)
1. A sense that deceit is slowly revealing itself (to hear a hissing snake).
2. A need for caution in expressing anger inappropriately (a hissing snake).
3. Progress will continue in spite of others (people hissing rudely).
To dream of hissing persons, is an omen that you will be displeased beyond endurance at the discourteous treatment shown you while among newly made acquaintances.
If they hiss you, you will be threatened with the loss of a friend.
