Will listening to a hypnotist CD as I go to sleep substitute for listening and actually getting hypnotized?

About a week ago, I was at a hypnotist show and was pulled up on stage. However, upon attempt to hypnotize me, it did not work and i was asked to go sit back down by the hypnotist. Despite this, I got a couple of his CD's to try listening to. Again, the CD's were unable to put me under. Now, my last hope is to try listening to the first track of the CD, that puts you under, while I go to sleep. My question is will this be just as effective, or am i not getting the same out of it I would normally?
