No, WILD does not directly impact DR. What does impact DR is mental blocks, such as worrying about DR. There’s a lot in your wording here that is revealing.
DR isn’t something you can force, you have to let it come to you. When you wake up, lay still for a few moments. If nothing comes, think of your evening from last night. Ask yourself, “what happened between then and now?” Questions are good, as your SC will work as hard as it can to answer them. If you get anything, even it’s just a fragment of a feeling write it down as quickly as you can. If you don’t get anything, relax and ask yourself why you aren’t remembering.
Above all, don’t tell yourself that you have lost your recall. Doing that will only give the signal to your SC to lose recall 
. You mind works on a series of basic commands, like a computer. If you want a specific result, you need to give it specific inputs.
Of course not, because you don’t believe that they are. Here’s the thing, if it gets to the point that you’re laying in bed repeating “I will remember my dreams” over and over you’re wasting your time. You have to believe it every single time you say it. Just telling yourself once and really meaning it will have much more impact than worthless words.
