Hey lucidinthesky,
I'm with you on that one. Pretty much everytime I drink or get hammered I always have lucid dreams or really intense vivid dreams. Do you have your LD's after drinking right after you fall to sleep or towards the moring time. I normally will have mine after sleeping for awhile. Plus being hung over makes it easy to sleep alot longer than normal so I'll have hours of lucid dreaming if I sleep way in after a night of drinking. Have you ever heard of the phenomenon that happens when you go to bed really drunk? I read that for the first few hours of sleep the aclohol makes it so you can't dream. you can't have REM sleep. But after the first few hours or more then the phenomenon happens where you'll have really long REM periods like of over 2 hours or more. It's like your body has to catch up on the REM you didn't get due to the alcohol. I'm going to do a little more research on this subject to know for sure but I think your body just goes into really deep sleep when you go to bed wasted and and then the more you sleep you can go into lighter levels of sleep in which REM occurs. That's probably why it's hard to wake someone up when they fall to sleep really drunk.
I've recently cut way back on drinking but when ever I do I know I'm in for a night of LD'ing
