Whats the earliest you have become lucid after falling asleep at night? I think the earliest for me is about 2 hours. I have alot of my lucids after about 3 and a half to 4 hours because of the method i use and i find that they are alot easier to stay in (even if you wanted to wake up it is very difficult) probably because you are in a deeper sleep than you would be in the later stages of rem. The down side to the earlier lucids is the lack of dream control but i prefer the early lucids because i can spend hours in them. (it's great)
