yes, i have done this once (i only tried once too). If you know how to properly use autosuggestion then Yes.

The thing is, apparently inbetween dreams everynight....we wake briefly and keep our eyes shut. Of course, we are so tired we dont remember. So try an autosuggestion like;

"I will be aware when I wake in the night" or something similar. "I will know when I awake" Maybe just an idea, it was somethig like that that worked for me.
