Is it possible to sleep after taking magic mushrooms?

If you’ve ever wondered how psilocybin and sleep interact, you aren’t alone. Many people notice that psilocybin changes how sleepy, alert, or dream-ready they feel for a few hours. Based on current evidence, these changes look to be short-term and tend to resolve as the acute effects wear off.

When taking classic psychedelics such as psilocybin (the main psychoactive substance contained in many species of hallucinogenic mushrooms) sleep can be impacted negatively by disrupting sleep patterns in the hours following ingestion.

Delays in REM Sleep

Psilocybin and sleep have a short, sometimes bumpy relationship. Right after dosing, it is common to feel more alert and to take longer to enter REM sleep. Most people return to their usual sleep pattern once the experience winds down. Human lab data and preclinical studies point to a delay in REM sleep on the first night after dosing and no signs of lasting sleep harm.

Psilocybin can disrupt short-term sleep quality by prolonging the onset of REM sleep in the hours following ingestion and promoting alertness and wakefulness. While it is possible to fall asleep while under the influence of magic mushrooms, it may be more challenging than usual. Anecdotal reports from users of psilocybin frequently describe difficulties falling and staying asleep immediately after taking hallucinogenic mushrooms, but sleep typically returns to normal once the effects of psilocybin subside.

What the Research Says

Short-term sleep disruption

• In a controlled human study where participants took psilocybin during the day and then slept that night, researchers observed a longer time to reach REM sleep and a trend toward less overall REM sleep. People also felt like it took longer to fall asleep, even though total sleep time changed little. 
• Complementing this, an animal study with carefully monitored brain activity found delayed REM sleep onset and reduced NREM maintenance for about three hours after psilocin, the active metabolite of psilocybin. Importantly, it did not show longer-term changes in overall sleep quantity.

Duration of effects

• In modern clinical pharmacology work, the subjective effects of oral psilocybin in healthy volunteers generally last about five to seven hours, with peaks around two hours and a clear taper toward baseline by the six to eight hour mark. That timeline matches many people’s lived experience of psilocybin and sleep feeling “mostly normal” later the same evening.
• Classic reviews and contemporary summaries likewise describe a typical window of psychoactive effects of roughly four to six hours, depending on dose and individual factors.

User reports

• Anecdotally, people often say psilocybin and sleep are an awkward combo on the same night. They describe feeling wired, needing more wind-down time, or waking during the night. Those reports mirror the lab findings on alertness and REM sleep timing, and they typically fade as the acute effects resolve. (Anecdotal synthesis, consistent with cited trials.)

Long-term effects on sleep

• Controlled studies to date have not found evidence that a single psilocybin experience harms long-term sleep architecture. The daytime human study documented REM timing changes only for the first post-dose night, and the preclinical work found no enduring changes in sleep quantity. Broader clinical safety reviews also show that common acute effects tend to resolve within 24 to 48 hours.

Practical tips

• Avoid bedtime dosing. Because psilocybin can boost alertness and delay REM sleep for a few hours, it is best not to take it right before trying to sleep. Plan your session so that the main effects are over well before your usual bedtime. Many people aim for a morning or early-afternoon start. This helps protect sleep quality and keeps your circadian rhythm steady.
• Give yourself a buffer. If you are exploring psilocybin in a legal, supervised context, allow at least six to eight hours, plus calm integration time, before lights out. That window aligns with typical effect durations seen in clinical pharmacology studies.
• Support sleep hygiene. Low lighting in the evening, screens off an hour before bed, gentle movement or breathwork, and a light snack if you are hungry can help nudge your body toward sleep after an activating day.
• Mind your stimulants. Caffeine, nicotine, and other stimulants can stretch that alert window. Keep them modest or skip them on session days, especially later in the afternoon.
• If sleep does wobble, zoom out. One restless night is common when psilocybin and sleep coincide on the same day. Most people slide back to their baseline the following night as the system resets.

Detectability and Timelines

Pharmacokinetic studies show that psilocybin converts to psilocin quickly, peaks around two hours, and declines thereafter, with subjective effects typically subsiding by about six to eight hours. Biological detection windows vary by test and are different from how long you feel the drug. In other words, “feeling back to normal” does not equal “nothing detectable in a lab test,” and those lab windows can extend beyond the time you feel effects.

Why this matters for you

If you care about psilocybin and sleep, plan your timing so your sleep quality does not take a hit. The data point to a temporary shift in REM sleep on the first post-dose night. Protecting your evening wind-down improves sleep quality and helps your next-day mood and energy.

FAQs 

Can you fall asleep on psilocybin? 

Sometimes, but it is usually harder than usual. 

Will it wreck your sleep long-term? 

Current evidence says no. 

Does it change dreams? 

REM timing can shift on that first night, which can feel like dream changes.

Bottom Line

Psilocybin and sleep can clash in the short term, especially around REM sleep timing and perceived alertness, but the effects are brief and typically resolve after the experience ends. Take psilocybin earlier in the day, build in a long wind-down, and you will give your sleep quality the best chance to stay on track.
