Dream meaning of abyss
When you face the abyss, it means you are at a point where the next step is personal darkness or tragedy. You are at a momentous point in
your life.
To dream of looking into an abyss, means that you will be confronted by threats of seizure of property, and that there will be quarrels and reproaches of a personal nature which will unfit you to meet the problems of life.

Among the Celts and other peoples, the abyss was inside mountains; in Ireland, Japan and the South Sea islands, it was at the bottom of seas and lakes; among Mediterranean peoples it was just beyond the horizon; for the Australian aborigines, the Milky Way is the abyss par excellence.
The abyss is usually identified with the ‘land of the dead’, the underworld, and is hence, though not always, associated with the Great Mother and earth-god cults.
An abyss is a natural symbol of emptiness and meaninglessness. It can also represent the need to detach oneself from an overwhelming condition or relationship.
The majority of primitive peoples understood abysses as various deep marine or terrestrial features. To the Celts, the abyss was found inside the mountain; in Ireland and Japan it was located at the bottom of the sea or lakes; and among the Mediterranean peoples it was beyond the horizon. Each individual has their own problems and own daily abyss (in which they occasionally fall victim to anxiety). Conflictive situations, if not addressed promptly, can become “abysmal.” Thus, this dream represents you are on the verge of something but you are afraid to take the plunge.
It is important to find out what that fear is about and why you feel so bad. When the abyss is dark it likely symbolizes your unknown Self.
If you are also anxious, you will not be pleased about what your feelings and hidden fears have to tell you. Dreams about abysses are often accompanied by vertigo.
This vertigo can be physical if you are lying on the edge of the bed; emotional, when you are unable to control your feelings about others; existential, due to absence of goals that give your life meaning; or directly related to your circumstances, perhaps because you need to make a decision without knowing which option is best. In the latter case, it is advisable to take enough time and choose well, thus avoiding any type of precipitation.
Usually an abyss forecasts financial difficulties. You must be very careful with any deals being considered in the next few the days. According to ancient beliefs, this dream portends problems in love, work, or health.
It is recommended to be cautious.
This is an obstacle dream.
If you avoid the fall, you will overcome your difficulties; but if you fall into the abyss, it is a warning that you must be extremely careful in your business dealings.
An abyss is created when the structure of a particular area is so out of reach, there is no immediate discernible sense of measurable boundaries. This fills us with anything from terror and dread to an excited desire for exploration. The bottomless pit of an abyss is a great symbol for the risks we must take in order to grow. When faced with an abyss in your dream, you have come to the edge of your known reality and are being asked to confront the unknown in a courageous way. The abyss is a symbol of the depths of your unconscious, which often inspires fear or avoidance.
