“…This side was pressed by the shadows and the suggestions of the night favored by the liberty of conscience what yield and throw off forever the mask of the right person that she had worn so long (Munro, 1887 ). Regarding the dissociative disorder, they are frequent in the general population (Maraldi, 2019 ), with about one-third of individuals reporting at least one dissociative symptom during their stressful moments. The etiology of dissociation has been psychologically linked to childhood trauma, but even the trauma feature points to the need of considering cognitive, psychopathological, and sociocultural features, other than the trauma itself in a comprehensive model of dissociative symptoms (Maraldi, 2019 ).…”

The etiology of dissociation has been psychologically linked to childhood trauma, but even the trauma feature points to the need of considering cognitive, psychopathological, and sociocultural features, other than the trauma itself in a comprehensive model of dissociative symptoms (Maraldi, 2019 ). Besides, there is an increasing amount of data lightening the complex association between dissociation and anomalous sleep disorders such as recurrent nightmares, vivid and bizarre dreams, sleep paralysis, hypnagogic/hypnopompic imagery, and narcolepsy symptoms (Maraldi, 2019 ).…”

“…One more association between dissociative symptoms and sleep is raised when it is known that sleep hygiene may be very useful to the treatment or prevention of dissociative symptoms (Maraldi, 2019 ). It is a diagnostic challenge, as the principal differential diagnosis of Lady Macbeth's is between a vivid SW and a DD, not exclusively.…”

“…The most detailed data could be read in some plays as in The Tragedy of Macbeth (Shakespeare, 1988 ). Night walking could be interpreted at this period as a prophetic or spiritual moment in which the individual was believed to be under the influence of strange or paranormal forces (Kocher, 1954 ; Maraldi, 2019 ). For some it was considered a prophetic or ecstatic state, but for others it was the result of a badly conducted baptism ceremony, consequently, they were often called the ill-baptized (Munro, 1887 ).…”

“…These variables are creativity , intuition , extraversion and dissociative disorders (e.g., Czekóová et al., 2018 ; Rabeyron et al., 2018 ; Thalbourne and Haraldsson, 1980 ). However, these variables present unstable statistical behavior because other research has not demonstrated significant correlations (e.g., Maraldi, 2019 ; Swami et al., 2011 ).

Researching unexplained phenomena: empirical-statistical validity and reliability of the Multivariable Multiaxial Suggestibility Inventory-2 (MMSI-2)

Anomalous phenomena are unexplained occurrences, such as paranormal experiences, that challenge the ontological bases of current scientific knowledge and are considered scientifically impossible. Problematically, some scientific research yields significant statistical results in favor of the existence of telepathy , precognition , mind-matter interaction , and mediumship. The current study presents and statistically justifies the Multivariable Multiaxial Suggestibility Inventory-2 (MMSI-2), a new psychological instrument to measure and detect the main psychological explanations for anomalous experiences. A nonprobabilistic sample of 3,224 subjects without a psychiatric history were recruited from the general population of Spain. Exploratory factor analysis (EFA) was used to examine the internal structure of the MMSI-2's 174 items. Direct oblimin and promax oblique rotations were applied as criteria for axis rotation. Cronbach's alpha coefficients and their ordinal transformation were also calculated, and gender-differentiated scales for the raw MMSI-2 scale scores were developed. The first-order factorial solution yielded a total of 16 factors that explained 92.84% of the variance. Of these, 10 corresponded to the psychological variables cited in the background literature, four classified the anomalous phenomena according to their sensory mode, and two represented prototype control scales for this class of psychometric inventory. The higher-order EFA grouped the MMSI-2 scales into four macrofactors that together explained 97.737% of the variance. Satisfactory reliability rates were obtained (alphas>0.8). The full version of the MMSI-2 with 174 items is a valid and reliable psychometric instrument for evaluating anomalous phenomena and the theoretically concomitant psychological variables. Similarly, the scaling of scores can be used in psychological assessment as a screening tool to identify clinically suspected psychological variables.

The most widely used measure to quantify dissociative symptoms is the Dissociative Experiences Scale (DES). However, little information is available concerning its temporal stability. The purpose of this study was to assess the stability of DES scores after 4 years. A total of 316 respondents recruited from a general population in Brazil took part in baseline and follow-up (70.57% were men; mean age = 32.97, SD = 10.95, minimum = 22, maximum = 74). Temporal stability was assessed through test-retest correlations and mean-level stability analyses. We found that the DES total and subscale scores revealed moderate test-retest correlations, with small variations among the DES factors. No significant difference (p > 0.05) was found between average scores for times 1 and 2. Overall, DES scores are significantly stable over time. Future studies would benefit from an investigation of the correlates and predictors of dissociation at different time points.
