Dream Journal

I have insomnia and when I do not take sleeping pills, I go into a dream state. Yesterday, the whole night I was dreaming. I am able to recount only one of my dreams. I was driving a minivan to buy cigarettes and I crossed a bridge and after that I was driving on and on through a lush paddy field. I woke up without reaching the destination. I can’t find a single dream book which carries multiple interpretations. What does the dream signify? Do the bridge and the lush green paddy field signify new positive beginnings? Is a Freudian interpretation of anxiety in the unconscious a right one or is the dream a detour from the realities of life? Freud calls it as condensation and displacement. I don’t trust my unconscious with Freud. Am I authenticating my life in the existential Sartre’s- way?
