Barbiturate use is associated with decreased sleep time and dreaming; withdrawal leads to what?

• A. Vivid and excessive dreams
• B. Insomnia
• C. Decreased dreaming
• D. Normal sleep

Answer: (A)

When barbiturates are used chronically, they blunt REM sleep and dreaming. If the drug is then withdrawn, there is a rebound increase in REM activity, so dreaming returns with greater frequency and intensity. This REM rebound leads to vivid, sometimes unsettling dreams or nightmares, which is why the correct choice describes vivid and excessive dreams. In contrast, sleep may be disrupted during withdrawal, but the hallmark change tied to barbiturate withdrawal is the surge in REM dreaming rather than normal or decreased dreaming.
