Abstract (english)

Eleven healthy subjects, 9 females and 2 males aged 21-23, were submitted to all night polygraphic recording and awaken in REM (Rapid Eye Movements) sleep, randomly upon tonic or phasic REM. Immediately upon awakening subjects were asked about possible dreaming according to the standardized questionnaire. Seventy-seven dreams, i.e. 79% of all 97 REM awakenings, were reported and analyzed. There were no significant differences in reported frequency of dreamings after awakening, mood and dream content due to phasic/tonic REM sleep. Dreams from phasic REM were a bit more colorful. Predictor of morning remembering of dreams was meaninglessness, not meaningfulness of dreams, and, in lesser extent, good mood, colorfulness, dreams with words and phasic REM sleep.

Abstract (croatian)

Jedanaest zdravih ispitanika, 9 žena i 2 muškarca u dobi 21–23 godine, podvrgnuti su cjelonoćnom polisomnografskom snimanju i probuđeni iz REM spavanja, nasumično iz toničkog ili fazičkog REM-a. Odmah nakon buđenja ispitanici su upitani o mogućem sanjanju u skladu sa standardiziranim upitnikom. Analizirano je 77 snova koji su navedeni nakon pojedinačnih buđenja, što je bilo 79% od svih 97 buđenja iz REM-a. Nije bilo značajnih razlika u čestoći sanjanja nakon buđenja iz fazičkog ili toničkog REM spavanja, kao niti u raspoloženju i sadržaju snova. Snovi iz fazičkog REM-a su bili nešto slikovitiji. Prediktor jutarnjeg prisjećanja bila je besmislenost, a ne smislenost snova, a u manjoj mjeri dobro raspoloženje, slikovitost i fazički REM.
