I feel that I am aware enough to realise that something weird is happening, because I am very aware of my dreams and they tend to be very vivid.
Even though I don't think the technique one you use to get lucid dreams is what matters, it can't hurt to try other ways of inducing one.
So now I am going to try the EILD.

Have anyone else tried this technique?

And to make sure that my subconscious doesn't trick me that I am still dreaming I need a really logical and clear message. Do you have any suggestions?

I am thinking of "Look at your hands you are dreaming!" or "This is not a joke, you are dreaming!"

I am going to use my speaker-pillow so if it's true that you hear outside sounds while you are dreaming, then I am definitelly going to hear this message.

I usually DEILD, but if I fail the attempt, it sometimes leave me tired the rest of the day, and it's not worth risking that.

Thanks for your help =)
