Brought to the cold light of day

Does the highlighted sentence imply:

Stezaker’s work shows that, while nowadays everything (all our dreams) seems manifest (there seems nothing latent), the materiality (material-based quality) of collage can return the latent nature of unconscious processes to our media-based dreams?

Context:
If the operations of the dream-work led Freud to the untranslatable navel of the dream, then it could be said that Stezaker’s operations of cutting into and removing parts from images parodically reverses this process, his process of subtraction almost doing violence to the image so that it can be liberated from its obsolescence and gain a new significance. Stezaker’s work shows that, while there is nothing that hasn’t been brought to the cold light of day, the materiality of collage can return the rupturing force of unconscious processes to the mediatised sleep of dreams...

Claude Cahun’s performances to camera, rather than being an analysis of the signs of femininity in mediatised society, seem to be more about the transgressive potential of femininity in its oscillation between active (aggressive) and passive (appeasement) forces (Art and Psychoanalysis by Maria Walsh).
