Dreamfasting is a Gelflings way of sharing memories. In a dreamfast, memories are communicated to each other in a sort of stream of consciousness, a telepathic memory montage. SkekSil was known to have discovered a method of undermining this ability.
In Legends of the Dark Crystal: Volume 1: The Garthim Wars, Neffi dreamfasts with Larh to show him the horrors of the Garthim attacks on her village.
In The Dark Crystal: Age of Resistance, it is shown that particularly powerful or ominous dreamfasting can produce a graven image called a dream etching.
Firefasting works almost the same as Dreamfasting, but is instead done by Firelings. A Gelfling and a Fireling can firefast/dreamfast together, but the Fireling's hand will most likely burn the Gelfling in the process.
Firelings can also firefast with flames from other sources, such as candles.
