I just have to say I dont understand why I am reading so much about lucid dreaming = lack of sleep.

Lucid dreams have nothing to do with how often you wake up in the night. A vivid non-lucid dream has just as much chance as waking you up. Also, if you are waking yourself up to jot down the lucid dream after it has happened, then I don't understand this either.

A lucid is lucid because you are aware - you are 'awake' in the dream. Sure, people can barely remember what they had for dinner yesterday, but I certainly hope you can remember what you ate just a few hours ago. Lucid dreams shouldn't be any different. You should be able to remember all of your lucid dreams in the morning. Since when you are aware, you remember. If you can't remember your lucid dreams, are you sure you were lucid?
