Alcohol withdrawal nightmares are one of a set of uncomfortable symptoms associated with detoxing from alcohol.

The symptoms of alcohol withdrawal occur due to the correction of chemical imbalances in the brain triggered by alcohol abuse.

Unfolding over several phases, alcohol withdrawal symptoms are classified as mild, moderate, or severe. You may experience nightmares after quitting drinking, even in cases of mild alcohol withdrawal.

In most cases, alcohol withdrawal starts within a few hours of the last drink, causing acute withdrawal symptoms typically lasting for 5 days. Sometimes symptoms persist for longer. This is known as post-acute withdrawal syndrome.

Does Alcohol Withdrawal Cause Nightmares?

Research shows that both subjective sleep quality and dream quality is markedly impaired in patients presenting with alcohol use disorder.

These are the most commonly reported issues concerning sleep and alcohol withdrawal:

  • Vivid dreams
  • Distressing nightmares
  • Restlessness or alertness at bedtime
  • Inability to relax and sleep at bedtime
  • Interrupted sleep
  • Waking during the night
  • Excessive snoring
  • Sleep paralysis
  • Dizziness
  • Lightheadedness
  • Racing thoughts preventing you from sleeping
  • Waking feeling fatigued despite sleeping all night
  • Inability to sleep despite feeling exhausted
  • Sweating or shivering
  • Muscle tension
  • Anxiety at lack of sleep
  • Sleepwalking

Sustained alcohol abuse causes structural and functional changes to brain chemistry. Alcohol is a CNS depressant. As such, its presence disrupts some processes in both the body and brain.

Specifically, alcohol increases the amount of GABA that’s available for the brain to use. GABA (gamma-aminobutyric acid) is a neurotransmitter or chemical messenger. GABA slows the transmission of messages between other neurotransmitters. The brain normally produces GABA in response to stress. This explains why alcohol – in small quantities, anyway – induces feelings of contentment and relaxation.

Beyond this, though, GABA also suppresses other bodily functions, including consciousness and breathing.

It’s not surprising, then, that alcohol use disorder and alcohol withdrawal impacts sleep overall.

Many people feel an alcoholic drink before bed promotes sleep, and this may be the case at first.

The problem is, your body tries at all times to stay in balance – homeostasis – and alcohol disturbs this balance. Over time, your body and brain learn to tolerate this new order, but when you moderate your alcohol intake or stop drinking completely, your sleep cycle is disrupted as a result.

And this is where alcohol withdrawal nightmares can present.

According to the Sleep Foundation, there are four distinct sleep cycles. Each cycle occurs for a different reason over a different time period.

These stages can be broadly cleaved in two depending on whether it’s REM sleep (rapid eye movement), or NREM sleep (non-rapid eye movement).

The sleep cycles unfold as follows:

  • N1 (first sleep cycle): Lasting from 1 to 5 minutes, the first NREM cycle varies from person to person.
  • N2 (second sleep cycle): One of the longest sleep cycles, N2 lasts from 10 to 60 minutes, and does not involve rapid eye movement.
  • N3 (third sleep cycle): This slow delta sleep wave is again NREM sleep, lasting from 20 to 40 minutes.
  • N4 (fourth sleep cycle): The final sleep cycle involves REM sleep, lasting from 10 to 60 minutes. REM sleep accounts for 25% of total sleep, and dreams more commonly occur during this sleep cycle.

Alcohol can trigger an irregular cycle of REM sleep known as REM rebound. This occurs both in those who drink regularly, and in those with alcohol use disorder or alcohol dependence. The condition is nevertheless more prevalent in those with patterns of abusive drinking.

The dreams or nightmares experienced during alcohol withdrawal are just one symptom of your brain and body reacting to the absence of alcohol.

While harmless, the nightmares associated with alcohol withdrawal can be terrifyingly vivid and seemingly indistinguishable from reality.

How long can you expect these alcohol withdrawal nightmares to last, then?

What to do After Getting Nightmares After Quitting Drinking

Fortunately, you can expect any imbalance in your sleep cycle to recalibrate after a week or two of abstinence, assuming you are drinking regularly.

For those with alcohol use disorder, it may take several weeks of the uncomfortable REM rebound before you find your sleep cycle normalized.

If you are detoxing at home, resist the temptation to take a drink. It may well stop you getting nightmares that night, but you’ll be back to square one and faced with detoxing anew.

Withdrawing from alcohol in a medical detox center allows you to take advantage of medication to streamline withdrawal symptoms and lessen the intensity of cravings. Benzodiazepines can be prescribed short-term to counter some effects of insomnia, although benzos are strongly habit-forming.
