All participants signed informed consent for the collection and treatment of data prior to participating to the experiment. Each subject participated in two experimental sessions structured as follows: a) EEG montage; b) subjects were instructed to consider any distinct mental activity occurring during sleep as a dream experience; c) polysomnography (PSG) with planned-provoked awakenings; d) final morning awakening.In order to ensure comparability between the two experimental nights, each subject was required to keep regular sleep-wake schedule during the week preceding the experimental session. The compliance was verified by a sleep diary. Experimental sessions were separated by at least one week. Subjects were also requested to abstain from caffeine and alcohol during the day of experimental session. The timing of the sleep–wake schedule during the protocol was adjusted to individual sleep-wake habits.Multiple awakenings were planned for each sleep cycle from REM sleep or NREM sleep after at least 5 min without stage shifts by calling out the first name of the subject through an interphone system. Participants were asked to report if they had (REC condition) or had not (NREC condition) a dream experience just before awakening. We did not collect dream contents to avoid an excessive activation that can interfere with subsequent sleep.DREAM categorization procedure2 = dream experience, 0 = No dream experience, -2 = No Experience or Experience without recallTechnical detailsDerivations with noise/artifacts are reported in the csv file.Data acquisitionThe PSG was recorded in a sound-proof, temperature-controlled room inside the sleep laboratory. A Brain Amp MR plus system (Brain Products GmbH, Gilching, Munich) was used to record EEG throughout the nights at a sampling rate of 250 Hz. The 28 unipolar EEG derivations placed following the international 10–10 system (C3, C4, Cp1, Cp2, Cp5, Cp6, Cz, F3, F4, F7, F8, Fc1, Fc2, Fc5, Fc6, Fp1, Fp2, Fz, O1, O2, Oz, P3, P4, P7, P8, Pz, T7, T8) were recorded by using an elastic cap (Easycap, Falk Minow, Munich) with sintered Ag–AgCl electrodes. The cortical EEG signals were referenced online to the averaged mastoids (A1, A2) and the ground electrode was located anterior to Fz (Fpz). Electrooculogram (EOG) and submental electromyogram (EMG) channels were also recorded and referenced to mastoids (A1, A2). EEG signals were analogically high-pass filtered with the time constant of 0.3 s and lowpass filtered at 30 Hz. A notch filter was applied (50 Hz). Electrode impedance was fixed below 5 kΩ.Language: Italian.Data preprocessingN/A<br>

实验设计
本研究共纳入20名年龄介于18~30岁的被试，所有参与者在参与实验前均签署了数据采集与处理的知情同意书。每名被试需完成两次实验流程，具体如下：
a) 脑电（EEG）导联安装；
b) 告知被试将睡眠期间出现的任何明确心理活动视为梦境体验；
c) 采用计划主动唤醒方案的多导睡眠图（polysomnography, PSG）监测；
d) 晨间最终唤醒。
为确保两次实验夜间数据的可比性，每名被试需在实验前一周维持规律的睡眠-觉醒作息，依从性通过睡眠日记进行验证。两次实验间隔至少一周。被试还需在实验当日避免摄入咖啡因与酒精。实验期间的睡眠-觉醒时间安排将根据个体睡眠习惯进行调整。
研究计划在每个睡眠周期中，当快速眼动睡眠（REM）或非快速眼动睡眠（NREM）持续至少5分钟且未出现睡眠阶段转换时，通过对讲机呼叫被试姓名以实施唤醒。参与者被要求报告觉醒前是否存在梦境体验（REC组为有梦境报告，NREC组为无梦境报告）。为避免过度激活影响后续睡眠，本研究未采集梦境具体内容。
DREAM数据集分类规则：2=存在梦境体验，0=无梦境体验，-2=无睡眠体验或有体验但无法回忆

数据采集
多导睡眠图（PSG）监测在睡眠实验室的隔音控温房间内完成。采用Brain Amp MR plus系统（德国慕尼黑吉尔兴的Brain Products GmbH公司）整夜采集脑电信号，采样率为250Hz。通过搭载烧结银-氯化银（Ag-AgCl）电极的弹性帽（Easycap，德国慕尼黑Falk Minow公司）安装28个单极脑电导联，导联位置遵循国际10-10系统，包括：C3、C4、Cp1、Cp2、Cp5、Cp6、Cz、F3、F4、F7、F8、Fc1、Fc2、Fc5、Fc6、Fp1、Fp2、Fz、O1、O2、Oz、P3、P4、P7、P8、Pz、T7、T8。皮层脑电信号在线参考双侧乳突平均电位（A1、A2），接地电极位于Fz前方（Fpz位置）。同时记录眼电图（EOG）和颏下肌电图（submental EMG），参考电极同样为双侧乳突（A1、A2）。脑电信号采用模拟高通滤波（时间常数0.3s）和低通滤波（截止频率30Hz），并施加50Hz陷波滤波。电极阻抗维持在5kΩ以下。
