Excessive yawning can be described as the experience of repeated, intensified, overly frequent, and spontaneous yawning despite a complete absence of genuine sedation or sleepiness.

Excessive yawning is often accompanied by other coinciding effects such as increased salivation and a runny nose. It is most commonly induced under the influence of moderate dosages of tryptamine psychedelic compounds, such as psilocybin, 4-AcO-DMT, 4-HO-MET, and ayahuasca.
