Is lucid dreaming safe?

Updated 16 October 2026 · 6 minute read · By WILD

Short answer: For most people, having lucid dreams appears to be safe. The main concerns researchers raise are about the methods: waking yourself up on purpose can break up your sleep. People prone to dissociation or psychosis are advised to be cautious. Practise a few nights a week, protect your sleep, and stop if it makes you feel worse.

What do researchers say about lucid dreaming safety?

Lucid dreaming is a natural experience: about half of people have had one (Saunders et al., 2016). Researchers have even held two-way conversations with lucid dreamers during REM sleep, with dreamers answering by eye movements, in four labs across four countries (Konkoly et al., 2021).

The open questions are about doing it on purpose and often. Two review papers have asked researchers to slow down and look for side effects before recommending lucid dreaming widely (Vallat & Ruby, 2019; Soffer-Dudek, 2020).

What are the possible risks?

• Broken sleep. Methods that wake you in the night “disturb sleep by increasing its fragmentation” and can shorten it (Vallat & Ruby, 2019). People who induce lucid dreams often report more sleep problems, although it is not clear which causes which (Soffer-Dudek, 2020).
• Dissociation. In one long-term study, people who deliberately induced lucid dreams showed a rise in dissociative and schizotypal experiences, such as feeling detached from yourself or your surroundings. The author calls this a direction for research, not a proven effect (Soffer-Dudek, 2020).
• Psychosis. Lucid dream practice may strengthen hallucinations in people with a psychotic illness, so caution is advised for them (Vallat & Ruby, 2019; Soffer-Dudek, 2020).
• Sleep paralysis. Methods like WILD pass through the state where sleep paralysis happens. It is harmless but can be frightening. See the sleep paralysis guide.
• Supplements and devices. Substances and brain stimulation sold for lucid dreaming raise their own safety questions (Vallat & Ruby, 2019). WILD does not use or recommend them.

Who should be careful?

• People with a psychotic illness, or who often feel detached from themselves or reality.
• People with insomnia, a sleep disorder or a job where tiredness is dangerous, such as driving or shift work.
• Anyone whose sleep or mood gets worse after starting.

If that is you, speak to a GP before you start.

What are the possible benefits?

People practise lucid dreaming for the experience itself, for creativity, for rehearsing skills and as a way to face nightmares. The evidence for these benefits is still limited. Vallat and Ruby (2019) point out that some of them, such as rehearsing movements, may also be reached while awake, and that other techniques for nightmares already work well without disturbing sleep. Be wary of anyone promising more than the research shows.

How do you practise lucid dreaming safely?

1. Protect your sleep first. Keep regular bed and wake times and get enough hours.
2. Limit night waking. Use wake back to bed two or three nights a week, not every night.
3. Keep it light. Curiosity works better than pressure, and a missed night is not a failure.
4. Stay grounded by day. Time outside, people and ordinary routines balance the night practice.
5. Stop if it harms you. If you feel more tired, anxious or detached, pause and speak to a GP.
