I heard that LDing is short of short even when its all night...[/b]
whoever told you that must not know how to ld very well! I have lds that are 15-20 min. some other people have even longer than that!
how much does waking 4-5 hours after you sleep help?? [/b]
You dream mostly in REM sleep (Rapid Eye Movement) but you dont have REM sleep all night, you have it at certain periods in the night. Your first period of REM is 90 min after you fall asleep and is only 10 min long. So with how your wilding you would have to wild for 90 min to get a 10 min lucid. not very fun at all and it takes alot of concentration. As you sleep through the night your periods of REM sleep get longer and closer together. making it possible to complete a wild sooner and have a longer ld that is why they say at least 4-5 hours, but you need to find a time that is best for you definatly makes it easier though!
Any advice on how to stop manual breathing??[/b]
what works for me is ignoring the breathing altogether.try thinking of somthing else a little more constant. like a clock ticking.

good luck with your wilds!
