Hypnagogic State Use
Role
The hypnagogic state has been deliberately exploited by creative practitioners since at least Thomas Edison — who famously napped holding ball bearings that would fall and wake him as he entered hypnagogia, allowing him to capture the creative associations of the hypnagogic state before sleep erased them — and across a range of creative and scientific figures including Salvador Dali (who used the same technique with keys), Nikola Tesla (who used hypnagogic imagery as a design simulation environment), and Edgar Allan Poe (who credited hypnagogic visions as sources for his fiction). The specific loosening of associative constraint that characterizes hypnagogia — the relaxation of the logical connections that waking cognition requires — makes it the most direct access point to the remote associations that deliberate thinking cannot reach.
