You won't be having much logical thought in the average dream. You pretty much have to either ingrain a certain RC or behavior so it's just second nature to you (no thinking required), or (the easier option) increase your wakefulness before dreaming. Have you tried WBTB much? When I first started trying to LD, I thought people were crazy to get up in the middle of the night, but then I tried it and it really helps wake your brain up. Then you may get a hint of rational thinking in a later dream. Throw in some SSILD with it and your odds go through the roof.
