Sleep cycles

Title made more explicit (was: Night). I moved this thread from the Quest forum into the First Steps cause I found this question was interesting for beginners.

I need help understading about sleeping cycles. Like REM and then every 90 minutes changes or something like that and NREM any help would be greatly apretiated!

It looks like Wikipedia has some info on sleep cycles. :content:

Does that help?

Thanks

You have also some explanations on the LD’ing guide of the LD4all main page. Click the “What” button, then read the chapter “sleep”.
