A baptismal font is a symbol both of acceptance into a spiritual life and of a washing away of the past and of initiation into a new way of being.
Psychological / emotional perspective: The two meanings of font come together on an emotional level. As a font is a receptacle for water it suggests feeling and security, as a typeface used in printing it suggests knowledge.
Material aspects: The commercial meaning of font as a form of lettering can give rise to images in dreams particularly in relation to the workplace.
To be changing a font would suggest doing things differently, whereas not being able to load the correct font suggests a difficulty in getting matters into perspective.
Another dream connected with the inside of a sacred building. It is not a fortunate omen.
