Dreamkeys are trapezoid-shaped objects required to unlock the boss battle for each dream realm.
Each key represents a numeral on the dream realm’s clock, once the clock is complete it will chime and unlock the dream realm’s boss.
Four of them are found in each of the dream realm's nightmares, making a total of 12 per realm and a grand total of 72 in all.
