Question One, if I pick a particular place or scernario I want to dream about, and I tell myself I will dream about it, is it likely to work?

Ex. I want to dream about being in a German Trench of WWI, If I lay there and tell myself I will have a dream of me in the Trenches, would I likely have a dream about that?

Question Two, if I did this, and I did have a dream about the German Trenches am I more likely to go lucid?

Thanks for helping out everyone!
