I find it to be best, if you are sure, that you could be dreaming. I mean, have this ever happen to you in a LD? You were 100% sure that you are awake, but you RCed anyway and you had 6 fingers? It happens to me all the time. I think it happens, because when I read a thread, I think to myself "wow, that may work for me, I gotta try, even if I don't think so". Then I do it, just in case. Just to be sure. And it does work. With RC, or with rolling out ot my body while WILDing...

If you think of that, it's fairly easy to believe at any moment, that you could be dreaming. But if you can't, then RCing anyway, just in case works as well.

During day, you can think "well, I could be awake, but I RC anyway". But you see, even when I think that, I still believe, that I could be asleep more, than I believe to be awake.
