Based on the Social Simulation Theory of dreaming (SST), we studied the effects of voluntary social seclusion on dream content and sleep structure. Specifically, we studied the Compensation Hypothesis, which predicts social dream contents to increase during social seclusion, the Sociality Bias – a ratio between dream and wake interactions – and the Strengthening Hypothesis, which predicts an increase in familiar dream characters during seclusion. Additionally, we assessed changes in the proportion of REM sleep. Sleep data and dream reports from 18 participants were collected preceding (n = 94), during (n = 90) and after (n = 119) a seclusion retreat. Data were analysed using linear mixed-effects models. We failed to support the Compensation Hypothesis, with dreams evidencing fewer social interactions during seclusion. The Strengthening Hypothesis was supported, with more familiar characters present in seclusion dreams. Dream social interactions maintained the Sociality Bias even under seclusion. Additionally, REM sleep increased during seclusion, coinciding with previous literature and tentatively supporting the proposed attachment function for social REM sleep.

“没有人是孤岛”：社交隔离对社交梦内容和快速眼动睡眠的影响

基于梦的社会模拟理论（SST），我们研究了自愿社会隐居对梦内容和睡眠结构的影响。具体来说，我们研究了补偿 假说，它预测社会隐居期间社交梦的内容会增加，社会性 偏差（梦和醒来互动之间的比率）和强化 假说，它预测隐居期间熟悉的梦中角色的增加。此外，我们评估了 REM 睡眠比例的变化。在之前（n  = 94）、期间（n  = 90）和之后（n = 119) 隐居静修。使用线性混合效应模型分析数据。我们未能支持补偿假设，梦想表明隐居期间的社交互动较少。强化假说得到支持，隐居梦中出现了更熟悉的角色。即使在隐居状态下，梦想的社交互动也保持着社交偏见。此外，隔离期间快速眼动睡眠增加，与之前的文献一致，并初步支持社交快速眼动睡眠的建议依恋功能。
