Sand Trance
The provided source material does not describe a specific practice known as 'Sand Trance' used for summoning or riding sandworms. The text details the dangers of harvesting melange due to rhythmic activity attracting worms, but attributes no trance state or vocal control to the Fremen for this purpose. Instead, the source explicitly defines 'spice trance' as a separate phenomenon: an overdose of melange gas used by the Bene Gesserit and Fremen to initiate clairvoyant visions, access genetic memory, and heighten prescience.

Lore & Background
It states that harvesting melange is hazardous because rhythmic activity on the desert surface attracts worms up to 400 meters (1,300 feet) in length, which can swallow mining crawlers whole. The Fremen are described as having learned to co-exist with these creatures and harvest spice manually for their own use or smuggling, but no mechanism of control via trance is mentioned.
In Their Own Story
The source contains no narrative about a character entering a trance to ride a sandworm. It does describe 'spice trance' in the context of overdose: Alia subjected herself to such an overdose late in Dune Messiah to enhance prescient visions, but this led to her descent into Abomination. In Children of Dune, Leto II and Ghanima resisted undergoing this trance due to fear of the same fate. When forced upon Leto at Jacurutu, he survived and remained in control, seeing the Golden Path, unlike Alia.
Reader's Guide
The source provides no guide for summoning or riding sandworms via trance. It notes that spice can be mixed with food or used as an inhalant. In extremely high dosages, such as the aerosolized gas standard practice for Guild Navigators, the drug alters physiology and induces a 'spice trance.' The text warns that withdrawal from melange is fatal and describes the intense psychotropic effects used by the Bene Gesserit and Fremen to access genetic memory, not to control desert fauna.
Did You Know?
- Melange is highly addictive, and withdrawal means certain death; Paul Atreides described it as a poison that won't kill you unless you stop taking it.
- Extensive use of the drug tints the eyes to a dark shade of blue called 'blue-in-blue' or the Eyes of Ibad, a source of pride for the Fremen.
- Guild Navigators use aerosolized spice gas in extremely high dosages, which alters their physiology into elongated figures with finned feet and membranous hands.
- Alia's descent into Abomination was caused by subjecting herself to a 'spice trance' (an overdose) late in Dune Messiah to enhance her prescient visions.
