People often dream that they have an exam and they have not reached the exam center even after a lot of hard work, or have not written anything in the exam.Such type Dream are symbolic image of threshold guardian which is not let you cross your own living horizon. Everyone has to cross the threshold.The threshold guardian is symbolic of a barrier holds you back.

Myths, like dreams, are products of the imagination. And there are two orders of dream, the simple personal dream, in which the dreamer becomes involved in adventures reflective only of his own personal problems, the conflicts in his life between desires and fears, driving wishes and moral prohibitions, and similar materials that are typically dealt with in a Freudian psychoanalysis. There is also another dream level that can be thought of as that of vision, where one has transcended the sphere of a merely personal horizon and come into confrontation with the same, great, universal problems that are symbolized in all great myths.

For example, when disaster strikes, when you meet with a great calamity, what is it that supports you and carries you through? Do you have anything that supports and carries you through? Or does that which you thought was your support now fail you? That building myth, of your life.
