Thanks for the support arch, to be honest I was way more worried cleaning my head and imagine the picture for MILD that I didn't even notice that my body was shutting down. It was a sudden burst of energy and then nothing. 5 secs later another burst and I entered in a lucid dream.

Yeah, I thought it could be that, but my first lucids were DILD ones, that's why I got confused. Maybe it's because my mind is still trying to make me loose lucidity that it always creates a false awakening in hopes I get distracted (funny when the lucid dream ended I ended up in a FA in which I was panicking for not being able to find my DJ to record the dream xD).

Guess I will try WILD again, I never had even tried performing it after 6 hours of sleep, so I hope it will work again
