To dream of a comic book represents storytelling or daydreaming of incredibly powerful feats. Telling or hearing stories where everything is amazing or powerful. A wish to take part in an incredible or odds defying experience.
Negatively, comic books may reflect too much focus on showing off incredible power and not enough on realistically confronting problems with the resources you currently have. Feeling that being incredible or too powerful is the only way you can be interested in solving a problem or make someone like you.
Example: A woman dreamed of seeing herself wanting to buy some comic books. In waking life she got dumped by her boyfriend for being too much of a party girl and wanted to impress her ex with how much she had changed by getting amazing grades in school.
