Dreaming of ammonia means you are encountering an irritating situation that you would avoid at all cost. The situation could be a relationship gone bad with spillover effects on your current friends and family. To ease the difficulties, open up your life to bring in new hobbies and company to replace the stink.
The ammonia in your dream may represent deep-seated anger, resentment or frustration that you have not expressed in your waking life. It can also symbolize an unconscious fear of something on the horizon or an impending confrontation with someone who scares you.
Smelling ammonia in a dream could also signify a problem needing to be cleaned up as soon as possible like when you’re working on a project and find out there is an error that could lead to a catastrophic failure.
