Because trazodone affects serotonin receptors involved in regulating sleep stages, some users notice changes in dream vividness or recall. This is generally not a safety concern, but if nightmares become frequent or distressing, discuss it with your prescriber — a dose or timing adjustment sometimes helps.
Can trazodone cause vivid dreams or nightmares?
Short answer: Some people report more vivid dreams while taking trazodone, likely related to its effect on sleep architecture, but this is not dangerous — persistent nightmares are worth mentioning to your prescriber.
