“The book “’Traumgedanken’ (“Thoughts on dreams”) contains a collection of literary, philosophical, psychological and scientifical texts which provide an insight into different dream theories.
To ease the access to the elusive topic, the book is designed as a model of a dream about dreaming. Analogue to a dream, where pieces of reality are assembled to build a story, it brings different text excerpts together. They are connected by threads which tie in with certain key words. The threads visualise the confusion and fragileness of dreams.”
