Dream suppression

From PsychonautWiki

Dream suppression can be described as a decrease in the vividness, intensity, frequency, and recollection of a person's dreams. At its lower levels, this can be a partial suppression which results in the person having dreams of a lesser intensity and a lower rate of frequency. However, at its higher levels, this can be a complete suppression which results in the person not experiencing any dreams at all.

Dream suppression is most commonly induced under the influence of moderate dosages of cannabis and other cannabinoids. This is due to the way in which they reduce REM sleep,[1][2] the phase of sleep in which the majority of dreams occur.[3]
