To explore hypnagogia.

Hypnagogia, the passage into sleep

Hypnagogia (from the Greek hypnos, sleep, and agōgos, leading) is the state you pass through as you fall asleep. Eyes closed, images rise on their own, sometimes a voice, a whole sentence, a feeling of falling. The psychologist Andreas Mavromatis devoted a book to it in 1987; our article on hypnagogia describes the state in detail.

One study links a plant directly to this state. In 1986, Mayagoitia, Díaz and Contreras had volunteers nap after taking Calea: light sleep increased, so did dream reports, and the researchers read them as hypnagogic imagery.

Herbs for the in-between

• Calea: among the Chontal, Schultes, Hofmann and Rätsch report (2001), the bitter tea is drunk, a few leaves are smoked, then one lies down quietly in a dark room until the pulse can be felt.
• Authentic blue lotus and blue lotus: in an Egyptian vessel shaped like the god Bes (2nd century BC), researchers found blue lotus in 2024, mixed with other plants; the museum’s curator sees in it a ritual drink “inducing dream and vision” (Tanasi et al., 2024). In South Africa, Zulu diviners use it for visions linked to the ancestors (Sobiecki, 2008).
• Imphepho: Xhosa healers burn it to induce and clarify dreams (Bührmann, 1984). Its smoke goes with the calling of the ancestors.
• Uvuma Omhlope and Ubhubhubhu: two plants of the Ubulawu family. Diviners in southern Africa wash with Uvuma to “see” in the spiritual sense (Van Wyk & Gericke, 2000); Ubhubhubhu is drunk at their initiation to sharpen memory and observation (Mönnig, 1967).
• Mugwort: as a light tea or in a dream pillow, for a first approach.
• Dream Elixir: seven dream plants, Calea, blue lotus and Yauhtli among them, gathered under the full moon of June 2025.
• Yauhtli: “the herb of the clouds” according to Hernández, the incense of Tlaloc among the Aztecs. One of our dreamers describes that passage with it:

Lingering a moment longer at the threshold

Hypnagogia lasts as long as falling asleep does. An evening tea, a dark room, no screen: a good setting to observe it. The images are watched as they pass; written down on waking the way you would write down a dream, then read again after a few nights, they show which ones come back.

To go further into the dream itself: herbs for lucid dreaming. Every dream herb, with what the sources say: our guide to lucid dreaming herbs. And our dream families: dream herbs, the Ubulawu roots.

Precautions

The first time, start with a small dose. Pregnancy and breastfeeding: abstain. If you take any treatment (antidepressants, anxiolytics, sleeping pills, heart medication): ask a doctor before any plant. After a plant that has made you drowsy, driving waits until the next day. The Ubulawu roots are taken at traditional doses: swallowed in capsules, at higher doses and outside any ritual, they brought confused and disturbing dreams (Sobiecki, 2012).
