The details of daytime dream experiences could be crucial in learning more about patients who suffer from narcolepsy.

A team, led by Carlo Cipolli, Department of Experimental and Diagnostic and Specialty Medicine at the University of Bologna, examined 30 drug-free cognitively intact adult patients with narcolepsy type-1 to assess the frequency of dream experiences developing during naps using the Multiple Sleep Latency Test (MSLT) and story-grammar analysis.

These methods enabled the investigaotrs to establish the structural organization of dream experiences developed during naps with sleep-onset REM period (SOREMP) sleep compared with their dream experiences during early and late-night REM sleep.

In the study, each patient was asked to report dream experiences developed during each MSLT nap, while 10 of the patients also spent voluntarily a supplementary night being awakened during the first and third-cycle REM sleep.
