hypnosis while during sleep

hi to all

i wanna ask about hypnosis during sleep, any body tried it or any one know about it how much it is effective, i research alot about it that it is really effective, when your conscious brain is sleeping but still your subconscious brain is fully active to get information...

Any body know about it, please let me know

I have no direct experience...but many therapists practice hypnotherapy. Perhaps seek out a qualified therapist.
