If you dream of election, it can mean you are very concerned with this process. You have a strong opinion on the nominees. Maybe you had personal interactions with the electoral process and this has permeated your thoughts.
Sometimes, you may even have dreamed on who won the election for 2020. Maybe you were influenced by the news, the surveys on exit polls, or the electoral campaigns. Your thoughts during the day can influence your dreams at night. These dreams are a continuation of the themes that occupied your mind during your waking hours.
If you dream of a candidate winning the election, it may not be a prediction of the actual results, but this dream could be just a projection on who you desire to see as the winner of the election.
