Dreaming is the subjective experience during sleep. A spontaneous thought is a thought that comes to one's mind involuntarily. This study investigated whether presleep focusing on a positive spontaneous thought enhanced the possibility of dreaming of the thought.
Ninety-seven participants were quasi-randomly assigned to an expression condition (focus on an spontaneous thought for 5-Min before sleeping; N = 45) and a control condition (think about anything for 5-Min before sleeping; N = 45). Participants completed a dream diary upon waking. Then, both participants themselves (the selfrating method) and external judges (the external-rating method) rated the correlation between the positive spontaneous thought and the dream.
The result of the external-rating method indicated that presleep focusing on positive spontaneous thoughts enhanced the possibility of dreaming of the thoughts. In addition, the external-rating method found that presleep focusing on positive spontaneous thoughts enhanced the possibility of dreaming of thoughts that were related to the positive spontaneous thoughts but not the positive spontaneous thoughts themselves.
These results supported the current concern theory which suggests that one's current concerns increase responses to cues related to the concerns implicitly. In addition, these results supported the continuity hypothesis which states that dreaming is in continuous with waking life, and thus the intensity of a daily concern may be related to the possibility of dreaming of the daily concern.
做梦是睡眠期间的主观体验。自发思维是一种不由自主地出现在脑海中的想法。本研究调查了睡前专注于积极的自发思维是否会增加梦到该思维的可能性。
97名参与者被准随机分配到表达组（睡前专注于一个自发思维5分钟；N = 45）和对照组（睡前思考任何事情5分钟；N = 45）。参与者醒来后完成一份梦境日记。然后，参与者自己（自评法）和外部评判者（外部评分法）对积极自发思维与梦之间的相关性进行评分。
外部评分法的结果表明，睡前专注于积极的自发思维会增加梦到这些思维的可能性。此外，外部评分法发现，睡前专注于积极的自发思维会增加梦到与积极自发思维相关但不是积极自发思维本身的思维的可能性。
这些结果支持了当前的关注理论，该理论认为一个人当前的关注会隐性地增加对与这些关注相关线索的反应。此外，这些结果支持了连续性假设，该假设指出做梦与清醒生活是连续的，因此日常关注的强度可能与梦到日常关注内容的可能性有关。
