Dream suppression

Dream suppression is 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 cannabinoids [1] and most types of antidepressants [2] [3] [4] . This is due to the way in which they increase REM latency, decrease REM sleep, reduce total sleep time and efficiency, and increase wakefulness. [1] [2] [3] [5] REM sleep is where majority of dreams occur. [6]
