Individual images like this have virtually no meaning without the context of the dream itself. It's wrong to think that such obscure images would have the exact same meaning in all dreams.
It doesn't mean anything, because the Haber process came long after the Bible was written.I'll give you a non-Biblical interpretation, though: If you dream about an ammonia factory, it means you're weird.
It means that you are obsessed with ammonia factories.
Assuming this "plant" is a factory, not a growing green plant... Ammonia is useful as a strong cleaner, but a plant/factory feels overwhelming and potentially toxic, which is exactly what ammonia fumes can be. So this dream might be a message from your mind, telling you that even though what you are doing might be useful, you are overdoing it. Too much of a good thing can be very harmful, indeed.
Give us the dream. The image by itself has virtually no meaning.
Ammonia production plants could symbolize one of two things. The first is an unconscious signal to use the restroom, as ammonia is one of the main ingredients in urine. The second, ironically, is a desire to clean something, as ammonia is also used as an ingredient in many types of household cleaners.
There are no common baby names in English that mean "ammonia factory"; however, names are not restricted to those commonly used.
There is not enough information to give a meaningful interpretation of this dream.
It is impossible to provide any meaningful interpretation without knowing what the dream was about. Dream interpretation is not similar to a psychic reading.
It is necessary to describe a dream before it can be interpreted. Dream interpretation is not the same as clairvoyance or mind reading; no magic is involved. Instead, dream interpretation investigates the meaning of symbols and metaphors found within the images of each dream. Such images and their interpretation are unique to each dreamer.
There is not enough specific information about the dream itself to suggest any meaningful interpretation.
A meaningful interpretation is not possible without some information about the dream itself. Dream interpretation is neither supernatural nor psychic but based on various psychological principles and the developing science of sleep research.
A meaningful interpretation is impossible without further information about this dream. Aging within a dream has no particular meaning in itself.
