Why are you dreaming about a coffin? The coffin symbolizes the death bed or an increasingly dark or cold atmosphere. Your consciousness is telling you that you are about to lose something or about to experience trauma and death.
Nightmares about coffins are also associated with heavy sorrows, depression, death itself, despair and human life’s aftermath. These dark dreams could mean our fear of death that awaits us. As they alarm us through the idea of our own demise during sleep time when we’re vulnerable, they may make us wiser in genuine attitudes towards life’s brevity and would make us more alert in the waking hour.
Live your life to the fullest if you dream about coffins and burials because it represents that we are all mortals and that time on this earth is too short.
