Comparaison de deux types de vision : synesthésie et hypnagogie

Abstract

When I was seven years old I discovered that I had been seeing the world differently from other people. My senses were joined. I was a synesthete. Over the years, I learned quite a bit about my synesthesia, but I was surprised in 2013 when I suddenly began to have another kind of vision, hypnagogic images. At first, I thought these new visions were part of my synesthesia, that I was seeing a new form, one I didn’t have a name for. But synesthesia needs a trigger, a trigger that causes us to see what we see. This form did not have a trigger, and that concerned me. In this paper I will explore the visual similarities and differences between my synesthetic photisms and my hypnagogic visions. I will compare the triggers or lack thereof, where I see the images, the ways in which the shapes I see appear, their colors, and their commonalities. I will discuss how the hypnagogic visions have changed, along with the fact that now both synesthetic and hypnagogic visions occur during the same experience, and that I have found other synesthetes who also have both synesthesia and hypnagogia.
