Dreaming of a chasm means facing a dark period in your life. If the chasm is deep and dark, it will take a long time for you overcome the challenges ahead of you. If you find yourself leaping over the chasm, then the unhappiness in you will fade with each rising sun. In the waking hours, do activities to warm your heart like having a cup of hot tea.
Knowing what to expect, learn how to better yourself and allow the darkness to wash over you instead of letting it linger.
