I dreamt it was Sigmund Freud’s birthday

And it is. He was born on May 6, 1856.

In the following pages, I shall demonstrate that there is a psychological technique which makes it possible to interpret dreams, and that on the application of this technique, every dream will reveal itself as a psychological structure, full of significance, and one which may be assigned to a specific place in the psychic activities of the waking state. Further, I shall endeavour to elucidate the processes which underlie the strangeness and obscurity of dreams, and to deduce from these processes the nature of the psychic forces whose conflict or co-operation is responsible for our dreams.

Sigmund Freud, The Interpretation of Dreams (1899)

In dreams I walk with you. In dreams I talk to you.
In dreams you’re mine. All of the time we’re together
In dreams, In dreams.

Roy Orbison, “In Dreams” (1963)
