In the world of dreams the rules of reality do not necessarily apply. Each dream is unique and it's a direct link to the soul and spirit. Psychology provides its own theories on what dreams mean, but so did tradition and the study of dreams for thousands of years before any relevant science had developed.
Dream Meanings - Abyss
To dream that you are in an abyss means that you will have some encounters with loved ones that will make you feel bitter. You may feel offended by the words and actions of people for whom up till now you have had great respect. If you dream that you are staring at an abyss from afar but can’t get close to it then be careful with your finances as you might lose some money.
