Hi Sasuke Cool name; I love Sasuke
If you ever feel the dream slipping away, try these techniques

-Focus on something in the dream. An item, a person, anything.
-Rub your hands together
-Spin
-Yell "INCREASE LUCIDITY" it sounds silly but i've heard it works.

I'm sorry but I don't know how to make your brain stop "mocking" you, but maybe you can fight back using these tips
Hope I helped
