---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. 
<br>
--Treatment group codes--
<br>
No treatment groups
<br>
<br>
---Experimental description---
<br>
See previous publications
<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.

--Data acquisition--
<br>
See published manuscripts
<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.
