Id vs. Superego
In this picture you can see my id demonstrating how much I wanted to eat my 4th birthday cake right away. However, my superego was thinking of how I knew the right thing would be to wait to blow out the candle and cut the cake like a normal person. My ego was able to mediate between the superego and the id, resulting in me waiting to get my piece of cake and enjoying it with the rest of my friends.
One of the earliest memories I have is of a nightmare I had in which a creepy clown was chasing me. Without knowing that this particular picture, which clearly shows my distaste for clowns, exists, Freud would've been able to analyze my dream and tell me that I do not trust or like clowns.
