I've found that saying "I will wake up after each dream period, and I will remember my dream" without internal dialogue seems to help but is difficult for me. The first time I tried it, I woke up at 4am. But once the sun came out I found it harder to go back to sleep. Now for some odd reason I wake up at 2am, could it be my subconsiousness? I read about it in the HILD tutorial but I'm too paranoid to mess around with my subconsiousness
