Foreshadowing is when you have like a dream or a vision into the future and it allows you to have a small hint of what will happen later on in the play but mostly a negatively used technique.

Romeo had a dream that he will be killed very young and this caused him to not want to go to Lady Capulets party because of his dream of death but he was persuaded to go.

Fate is when there is a greater power that predetermined what will happen to you in the future. They can’t change what will happen and it can’t be avoided which is something like destiny.
