The study by Nelson et al. has been criticized (Long & Holden, 2007), however, which recently inspired us to carry out a follow-up study in a different setting to address some of the criticism (Kondziella, Dreier & Olsen, 2019). For example, Long and Holden pointed out that 40% of the people with NDE in the Nelson study denied ever having experienced an episode of REM intrusion, suggesting that there may be a link between the two phenomena, but not a 1:1 relationship (Long & Holden, 2007). In our crowdsourced survey, 106 of 1034 participants reported NDE according to a Greyson NDE Scale (GNDES) score ≥7, and 50 (47%) of these individuals fulfilled the criteria of REM intrusion according to almost the identical questionnaire that Nelson and colleagues had used (Kondziella, Dreier & Olsen, 2019). In contrast, only 17% of individuals without NDE reported REM intrusions. Based on multivariate regression analysis, we found that REM intrusion is a predictor of NDE (Kondziella, Dreier & Olsen, 2019). Thus, we confirmed the results of Nelson and colleagues, but also the limitation that this is not a 1:1 relationship.
