'''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''' can be described as a decrease in the vividness, intensity, frequency, and recollection of a person's dreams.
