It could be said that Rousseau’s philosophical reflection was nourished by an original trauma, since his mother died as a result of childbirth a few days after his birth and he always felt guilty for that, even though such a circumstance contributed to design his conception of moral conscience. On the other hand, Rousseau not only wrote the Dreams of a Lonely Walker (1776) but also connected his own personal experiences with the literary characters of Julie, or the New Heloise (1761). Kant, the author of a visionary’s Dreams of a Ghost-seer explained by Dreams of Metaphysics (1765), said that without daytime dreamers such as Plato or Rousseau there would be no room for the moral progress of humanity. For his part, Schopenhauer was convinced that a premonitory dream had saved his life, making him leave Berlin so as not to fall victim to the same epidemic that killed Hegel. Schopenhauer understood that, by dreaming while we sleep, we access another universe where the space-time coordinates do not exist, on that other side of the Veil of Maya where we will return when we die and we were before we were born, coming to describe our ephemeral life as the dream of a primeval will that homologates with the thing in itself Kantian, making good what was said by his admired Calderon regarding that life is a dream. Curiously, Freud preferred to deny that he had read Schopenhauer, rather than recognize Schopenhauer's obvious influence on fundamental points of psychoanalysis, such as considering our dream life the best point of access to the unconscious, as shown by Leonardo da Vinci’s Childhood Memory (1910)
