About your sleep cycle illustration
Dear Schlafgut, thank you for making all of these useful illustrations a few years ago. English Wikipedia is now using your diagram on the new article called Sleep cycle. If you see this message, perhaps you would be so kind as to explain: how did you construct the illustration? Is it based on another publication, on personal research, or an estimate of what a normal sleep cycle hypnogram looks like? Thank you very much and I hope you're doing well. groupuscule (talk) 19:05, 26 July 2017 (UTC)
