Hard time to get lucid

Ive been working for a month on WILDing. WBTB after different times and for different durations. Still, I dont get realy tired or dizzy by laying confortable and relaxed not thinking at all.

A few times I entered a dream, but only after at least one to two hours. And only one time I managed to RC and realize that Im dreaming.

I tried focusing on breathing a few times, but all the time I just start vibrating and feeling heavy, never entered SP. A few times tho I started to feel like falling thru the bed. I never entered a dream this way.

And I also tried just closing my eyes laying relaxed and observe what comes up in the black.

This way is the only I got lucid from awake state. But 90% of the time I just lie still for two hours without success. A few times recently when i tried I get totally awaken by hearing my own voice, talking to some guy that I see in my fantasy.

After this I just roll over and try to sleep as usual (which is much easier then laying down trying to be aware :) ), takes me about 25 minutes and Im dead sleeping again. But once in a dream I ignore dreamsigns and believe that it all is real, I even do RCs and I believe they are negative. haha I know its sick.

I know youll say Im just inexperianced and just need to continue trying. I know and I will, I will continue try the same techniques and also add some others to.

I realy need some good tips, how I can be aware without thinking and without getting into this fully awake state. Sometimes I feel like Im 100% rested, after trying to get SP and enter a dream for 40 minutes. Ive just come back after a 3 minutes toilet visit and 3 hours sleep before that! Hey whats wrong I should be dreaming by now!?
