---How to decode data files---
<br>
The files in the PSG directory are named according to the subjectID and the CaseNumber for each awakening. For example the file 10_0103.edf is associated with the third awakening (case 0103) from subject 10.

--Treatment group codes--
<br>
No treatment groups

---Experimental description---
<br>

<br>
--DREAM categorization procedure--
<br>
The original experiment categorized the dream reports according to the DREAM definitions.
<br>
<br>
---Technical details---
<br>
The data include a single EMG channel (called EMG1), which is a bipolar derivation of the standard LAT and RAT electrodes placed on the chin of the sleeping subject.
The data include two EOG channels (called EOGu and EOGl), which were placed in the American Academy of Sleep Medicine (AASM) recommended E1 and E2 positions below (l for lower) and above (u for upper) the lateral canthi.

<br>
--Data preprocessing--
<br>
Data were rereferenced to a common average reference and zero centered to adjust for the DC offset. Raw data can be requested in accordance with statements in published manuscripts.

---数据文件解码方法---

多导睡眠图（Polysomnography, PSG）目录下的文件命名规则为受试者ID+每次觉醒的案例编号。例如，文件10_0103.edf对应受试者10的第3次觉醒（案例编号0103）。

--治疗组编码--

无治疗组

---实验描述---

详见既往发表文献

--DREAM分类流程--

本原始实验按照DREAM的定义对梦境报告进行分类。

---技术细节---

本数据集包含1个肌电图（Electromyography, EMG）通道（命名为EMG1），该通道为放置于睡眠受试者颏部的标准LAT与RAT电极的双极衍生信号。
本数据集包含2个眼电图（Electrooculography, EOG）通道（命名为EOGu与EOGl），电极按照美国睡眠医学会（American Academy of Sleep Medicine, AASM）推荐的E1与E2位置放置，分别位于外眦下方（l代表下方）与上方（u代表上方）。
