What Your Childhood Halloween Costume Says About You, According to Psychologists

For many kids, Halloween is an opportunity to embody their favorite character or celebrity. "It's a way to be like, 'Hey, I can also be a part of [this world],'" Nasir says. "It's what we used to do as kids: we would play pretend. So we tap into our fantasy and imagination and we get to really participate with our physical body in something that we only see on the screen or read in books."

Whether you admired the Spice Girls or Anne Hathaway in "The Princess Diaries," Halloween opened the door to become part of their world. Depending on what they meant to you, personally, dressing up as a celebrity or character could have been an indication of your admiration for them or a way to fit in and get conversations started among friends.
