abstract dreaming.
for me, having synesthesia means having very abstract, monochrome often lucid dreams at night. these designs show some of the dreams I had. people, emotions and experiences appear in the form of moving, abstract objects instead of their actual, usual form. so a person might appear as a green pipe instead of a human body. it is extremly abstract but makes perfect sense while dreaming. Weirdly, the whole dream isn’t colourful but consists of different shades of only one colour always.
