Dream Problem

Better Dream recall. Better daytime-Awareness. Meditation. Finding Dream Signs. WBTB where you only get up for a few seconds, with or without additional Techniques.

Regular reality checks won't help you, unless it's coupled with WBTB of sufficient waking time. Even then it's effectiveness is very questionable. Keep in mind, during R.E.M. Sleep the regions, which handles self-awareness and other important cognitive functions, of your brain are pretty much deactivated or in very suppressed states. Thus, your day time habits and logical mind are unlike to be present. Only after WBTB you reactive these regions, but then you risk not being able to fall back to sleep if you stay awake for too long!
