They measured post-episode distress using a range of items, from post-episode rumination to interference with next-day functioning.<\/p>\n<p>The level of distress following sleep paralysis episodes was associated with features of the sleep paralysis episode itself. <strong>For example, the results showed that the more fear people felt during sleep paralysis episodes, the more distress they felt afterward<\/strong>.<\/p>\n<p>The researchers also found that <strong>sensory experiences during episodes of sleep paralysis predicted later distress<\/strong>. Feelings of threat and assault\u2014such as sensing a presence in the room, feeling pressure on the chest, having difficulty breathing, or having a feeling of imminent death\u2014were all associated with distress following sleep paralysis episodes. So, too, were vestibular-motor experiences, including feelings of floating or falling and out-of-body experiences.<\/p>\n<p>Cheyne and Pennycook <strong>speculate that the sensory experiences that come with episodes of sleep paralysis could exacerbate people&#8217;s fear<\/strong>, creating a feedback loop that enhances memories of experiences later on.<\/p>\n<p>Post-episode distress was also associated with a number of individual-level factors, including cognitive style, distress sensitivity, and supernatural beliefs about sleep paralysis.<\/p>\n<p><strong>People who held supernatural beliefs about sleep paralysis experiences also experienced greater post-episode distress<\/strong>. Those who had more analytic cognitive styles, on the other hand, experienced comparatively less distress after sleep paralysis episodes.<\/p>\n<p>Taken together, these findings show that both situational factors and individual factors contribute to these common, and often stressful, personal experiences.<\/p>\n<p>These findings are important, the researchers say, because they provide insight into a common experience of distress that is not well understood. Some participants lamented that their experiences of terror following episodes of sleep paralysis were often dismissed by clinicians.<\/p>\n<p>Given that a large percentage of people report some carryover effects on their functioning the next day,<strong> sleep paralysis could &#8220;make a significant contribution to the billions of dollars, worldwide, in costs associated with accidents, illnesses, and lost productivity associated with sleep disturbances,&#8221;<\/strong> the researchers note.<\/p>\n<p>The paper is titled &#8220;Sleep Paralysis Postepisode Distress: Modeling Potential Effects of Episode Characteristics, General Psychological Distress, Beliefs, and Cognitive Style.&#8221;<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Association for Psychological Science press release via MedicalXpress: Ever find yourself briefly paralyzed as you&#8217;re falling asleep or just waking up?
