Why can't I dream?
Approved answer
Possible Reasons for Lack of Dreaming
Various substances, including caffeine, alcohol, benzodiazepines, and some psychiatric medications, can interfere with REM sleep, which in turn affects the ability to dream. Additionally, sleep disorders such as narcolepsy, insomnia, and obstructive sleep apnea may lead to disruptions in sleep patterns, resulting in less coherent or fragmented dreams.
