Personally I would start somewhere between 15-30 minutes and adjust up or down from there based on results. I seem to have a better chance of DILD (as I've said elsewhere, my WILD is pretty much non-existent no matter what but I'm trying to work on it) after about a 5-10 minute WBTB, long enough to jot down notes about my last dream and get my head in the right place. I have tried them longer but it doesn't seem to increase my chances, and anything over 20ish minutes will make it harder for me to sleep. I have heard of 40+min WBTB but not me if I can help it. Then again I've only done the longer ones a couple times just because most nights I don't want to risk being stuck awake. |
