OBJECTIVE: To evaluate the frequency, determinants and sleep characteristics of
lucid dreaming in narcolepsy. SETTINGS: University hospital sleep disorder unit.
DESIGN: Case-control study. PARTICIPANTS: Consecutive patients with narcolepsy
and healthy controls. METHODS: Participants were interviewed regarding the
frequency and determinants of lucid dreaming. Twelve narcolepsy patients and 5
controls who self-identified as frequent lucid dreamers underwent nighttime and
daytime sleep monitoring after being given instructions regarding how to give an
eye signal when lucid. RESULTS: Compared to 53 healthy controls, the 53
narcolepsy patients reported more frequent dream recall, nightmares and recurrent
dreams. Lucid dreaming was achieved by 77.4% of narcoleptic patients and 49.1% of
controls (P < 0.05), with an average of 7.6±11 vs. 0.3±0.8 lucid dreams/ month (P
< 0.0001). The frequency of cataplexy, hallucinations, sleep paralysis,
dyssomnia, HLA positivity, and the severity of sleepiness were similar in
narcolepsy with and without lucid dreaming. Seven of 12 narcoleptic (and 0
non-narcoleptic) lucid dreamers achieved lucid REM sleep across a total of 33
naps, including 14 episodes with eye signal. The delta power in the electrode
average, in delta, theta, and alpha powers in C4, and coherences between frontal
electrodes were lower in lucid than non-lucid REM sleep in spectral EEG analysis.
The duration of REM sleep was longer, the REM sleep onset latency tended to be
shorter, and the percentage of atonia tended to be higher in lucid vs. non-lucid
REM sleep; the arousal index and REM density and amplitude were unchanged.
CONCLUSION: Narcolepsy is a novel, easy model for studying lucid dreaming.
