Ending something in a dream represents change, an ending or tragedy, or death.
Dreaming about ending something symbolizes this type of change or any development happening to the person’s life that ends up causing problems for them. Thoughts may also contribute to ending things in dreams as well with vivid waking thoughts and regrets.
Envisioning ending something in a dream usually signifies frustration stemming from problems encountered during conscious day-to-day life; it also especially often serves as the conclusion to an intolerable argument.
