Vivid Dreams

Vivid dreams are dreams experienced as unusually intense, detailed or emotionally charged, and remembered clearly on waking. They arise from REM sleep, so anything that increases REM pressure or fragments sleep near morning tends to increase them. Common triggers are straightforward: stress and anxiety, sleep deprivation followed by recovery sleep, pregnancy, fever, and REM rebound after stopping alcohol, cannabis or an antidepressant. Medications are a frequent and often unrecognised cause - beta blockers, some antidepressants, varenicline, and among supplements melatonin, 5-HTP and vitamin B6 taken before bed are all reported to intensify dream recall. In most people this is a curiosity rather than a problem. Two patterns matter clinically. Recurrent distressing nightmares that disrupt sleep and daytime function are treatable, and imagery rehearsal therapy has good evidence, with prazosin used in trauma-related nightmares. Dream enactment - physically acting out dreams with shouting, punching or leaping from bed - suggests REM sleep behaviour disorder, which needs neurological assessment because it carries an association with later neurodegenerative disease and poses an injury risk. Otherwise, the practical approach is unremarkable: consistent sleep timing, reducing evening alcohol, and reviewing the timing and dose of any supplement taken at night before assuming something is wrong.
