I agree with Skysaw regarding the question to his answer.

I also think that you should keep a DJ no matter what; I know its a hassle sometimes but it really helps towards getting a DILD. Im a WILDer; but its always good to have DILDs as a back up plan.

You sound like you're already pretty good at WILDing but it doesnt hurt to read all the info here at DVs on WILDing that you can. And you might already know that the key to mastering the practice of WILDing is through practice. The more you practice WILDing; the better you'll be at handling any future potential problems that you have or have had in the past.

And whenever you try summoning people/things in dreams; you have to know that it/they will appear at your will. As for a tip, visualize the image of the person/object perfectly in your head, then walk through a door or a corner and they/it should be there. Personally, I turn around, visualize person/object, then simply turn back around to see them. Remember, you have to really expect them to be there when you look, otherwise, they might not show up!
