In "Speak, Memory," Vladimir Nabokov describes the process of becoming aware of consciousness as a sequence of brief illuminations. These flashes of understanding initially occur at wide intervals but become more frequent over time. This progressive narrowing of intervals emphasizes the evolution of perception, allowing for a richer and more vivid experience of memory.

Nabokov suggests that as consciousness awakens, it transforms into solid blocks of perception. This development not only enhances the clarity of memories but also creates a complex relationship with them, making them both substantial yet elusive. The metaphor of bright blocks of perception captures the dynamic nature of awareness and the challenges of holding onto fleeting memories.
