Here is a great example from a mom on the Yahoo Group, who always thought she was sleeping, but now has proof she really had hypnotic amnesia!
I know there are lots of questions on here about sleeping through the tracks, and I just wanted to share my experience . . . . I thought I was one of those people who was sleeping through her tracks almost every time except for the first listen. Last night, DH & I were listening to Creating Anesthesia, and I “woke up” during center of the last time Kerry has you do the fingerdrop exercise in the track. I remember feeling all freaked out b/c I had been asleep, and I was thinking, “Oh shoot, I missed it all again.” But, I went ahead and followed Kerry through flipping back to Off, and then counting up to 3. After it was over, I asked DH how long I had been asleep (I have started snoring pretty badly when laying on my back in the last couple weeks, so it’s pretty clear when I’m sleeping v. just having my eyes closed). He was like, “You weren’t asleep–don’t you remember talking to me?” Apparently, after one of the times on the track when Kerry counts you up to 3 after doing a practice fingerdrop, DH asked me something, and I looked at him with my eyes open and said, “Shhhh, you’re not supposed to be talking.” I have NO RECOLLECTION of that conversation at all. None–I don’t remember anything after hearing Kerry explaining the idea of the switch until that final going into center when I “woke up.” Anyway, I just thought I’d share. Although I was taking comfort in hearing that lots of people sleep through the tracks with great results, this makes me feel even better to know that maybe sometimes when I think I’m sleeping, I really am just experiencing hypnotic amnesia.
