I sleep 8 hours from Monday to Friday, and I started to sleep 10 hours every weekend. Today is Saturday morning(after my first attempt to sleep extra 2 hours on weekends) and I remembered two long dreams(nightmare). Maybe it was just a placebo affect. Am I just wasting two hours of my life? Or will I have better dream recall every weekend? |

Well my science here might be a little dodgy, but I'm fairly sure we have REM cycles of roughly 100 minutes, however the first few hours of sleep are generally non-REM. We have dreams during REM periods, so by waking up after about 4.5, 6 and 7.5 hours most people will recall dreams. If you sleep for 10 hours, though, you will get an extra REM period than if you sleep for 8 hours, and because it is right at the end you will have almost 100 minutes of exclusive REM sleep, whereas say the cycle beginning after around 6 hours might be half REM and half non-REM. Therefore, yes sleeping in will probably help improve your recall, as you will have a huge chunk of REM sleep right before you wake up. I think I might have left something out but there we go . |

My best time frame for LDing is at 9 hours. More sleep seems to help. |

Personally, I normally sleep less than 8 hours - more like 7.5 hours - and then just wake up and if I force myself to sleep more I don't feel as refreshed. But sometimes I sleep more like 8 hours or even up to 9. I try not to oversleep too frequently because it sometimes messes up my sleep routine. |

This is weird, but I've noticed I normally have worse recall if I sleep too much. I don't know exactly whether this is exclusively related to the amount of sleep, but normally on weekends I tend to have worse recall. Don't take it too seriously though, because maybe it's also because on weekends I go to bed later. |

"If you must sleep a third of your life, why should you sleep through your dreams?"
Stephen LaBerge
One prevailing theory about sleep stages is the idea of sleep debt. As time passes, your body accumulates the need to restore itself. Sleep provides this restoration, but it is somewhat complicated. Deep NREM sleep operates to restore bodily fatigue. REM and dreaming operate to restore mental faculty. On top of that, there is a natural order of NREM first and REM second. Altogether, it is a delicate balancing act of loosely connected and asymmetrical factors. |

I am sure about illusion. I am not so sure about reality.
