Ben Ehrlich in Nautilus:
Santiago Ramón y Cajal, a Spanish histologist and anatomist known today as the father of modern neuroscience, was also a committed psychologist who believed psychoanalysis and Freudian dream theory were “collective lies.” When Freud published The Interpretation of Dreams in 1900, the science world swooned over his theory of the unconscious. Dreams quickly became synonymous with repressed desire. Puzzling dream images could unlock buried conflicts, the psychoanalyst said, given the correct interpretation. Cajal, who won the 1906 Nobel Prize for discovering neurons and, more remarkably, intuiting the form and function of synapses, set out to prove Freud wrong. To disprove the theory that every dream is the result of a repressed desire, Cajal began keeping a dream journal and collecting the dreams of others, analyzing them with logic and rigor.
Cajal eventually deemed the project unpublishable. But before his death in 1934, he gave his research, scribbled on stained loose papers and in the margins of books and newspapers, to his good friend and former student, the psychiatrist José Germain Cebrián. Germain typed the diary into a book, which was thought lost during the 1936 Spanish Civil War. In fact, Germain carried the manuscript with him as he traveled through Europe. Before his death, he gave it to José Rallo, a Spanish psychiatrist and dream researcher. To the delight of scholars and enthusiasts, Los sueños de Santiago Ramón y Cajal was published in Spanish in 2014, containing 103 of Cajal’s dreams, recorded between 1918 and his death in 1934.1 Translated here into English for the first time, these dreams, and Cajal’s notes on them, offer insight into the mind of a great scientist—insight that perhaps he himself did not always have.
A Common Dream
[Falling of pants]
I attend a diplomatic soiree and as I am leaving my pants fall down (Is it desire?)
[Drowning with daughter]
I take a walk by the bay (Santander?) and I fall into the water with one of my little daughters in my arms. I fight the waves, I am almost drowning, despite touching the seawall. The nightmare awakens me.
