To develop and validate traumatic dream scales by further utilizing The Sang Bok Lee Neurocognitive Dream Orientation Scales (Lee, Sang Bok: 2010, European Psychiatry) assessing the narrative dream contents.

2450 dream were collected form 870 Korean college students, Yongin, South Korea: 445 males (M age = 20.48 years, SD = 1.35) and 425 females (M age = 20.12, SD = 1.24). The collected dreams were analyzed by The Sang Bok Lee Traumatic Dream Scales that were designed to differentiate ordinary dreams from traumatic and PTST-related dreams.

The traumatic dreams were hypothesized as having frequently recurrent, unexpected, emotionally dreadful, and not actively coped by the dreamers.

759 dreams (31%) of 2450 collected dreams were found as traumatic or very/extreme anxious according to The Lee Anxiety Dream Scale (Mean = 4.56). Strong positive correlation was found between 759 traumatic dreams and independent variables of traumatic dream content (unfamiliar: r = .86, p = .0001; accidental: r = .81, p = .0001; dreadful: r = .93, p = .0001, and not coped by the dreamer: r = 0.86, p = .0001).

The contents of The Sang Bok Lee Traumatic Dream Scales were developed and validated; the results were associated with the previous publications - “Lee Acculturation Dream Scale for Korean-American College Students” (Lee, Sang Bok, 2005: Psychological Reports, 96, 454–456), The Sang Bok Lee Neurocognitive Dream Orientation Scales for Screening Traumatic and PTSD Related Dreams, and The Lee Anxiety Dream Scales.
