Hi guys,
those methods don't work, there's no scientific proof that sleep-learning works, but there's much evidence that you won't get any result. You sure can't learn, say, differential and integral calculus by sleeping! (if you sleep during class you won't learn anything, I guess...

One thing is for sure: if you study before going to sleep, chances are you'll memorize more. So I believe that reading, practicing, or listening to some English before going to bed is much more helpful than doing so in the morning, for example. Learning about difficult subjects could be difficult because you might be tired at the end of the day, but reading a book or listening to some radio will sure help you improve your English.

PS: reading the above post about creativity reminded me that if you practice English before going to bed, you are more likely to dream in English, sometimes.
