If vivid dreams leave you exhausted, experts say the problem may not be the dreams but disruptions that prevent deep sleep

Feeling fatigued after dreaming is often linked to disrupted sleep patterns, especially during REM phases. During REM, the brain remains highly engaged, which prevents achieving deeper rest. If dreams are recalled, it signals that you woke while dreaming, interrupting the crucial restorative stages of sleep. This interference obstructs clearing adenosine, a natural sleep-inducing byproduct, making tiredness arise from your awakening moment rather than the dreams themselves.
