To dream of a mascot represents you or others that is trying to generate enthusiastic support for something. Trying to “drum up” support or get others behind behind a cause by making them feel that it’s most important. Wanting others to think that something is important.
Negatively, a mascot may reflect last minute desperation to get others to help you. Manipulating others feelings to your purposes. Trying to get support by making others feel sorry for you or scared for your well-being.
