Dream suppression can be described as a suppression of the vividness, intensity, frequency, and recollection of one's dreams. At its lower levels, this can be a partial suppression which results in one 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 one not experiencing any dreams at all.

In the context of psychoactive substance usage, this effect can occur when certain compounds are ingested before a person sleeps. It is most commonly experienced under the influence 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]
