The Complete Guide to Interpreting Your Dreams

by Stearn Robinson - Tom Corbett
You’re bottling up something you need to get off your chest if you dreamed of being deliri- ous; a sympathetic and trusty ear could avoid an embarrassing explosion, so try to find one.

If your dream featured others in a delirious state, you will get help from an unknown source.

To dream of being Delirious signifies danger through a secret; to see someone else in that condition means a friend trying to help you secretly.
