Electric like shock and buzz when I re-enter

Hi, I started exploring AP because I have always had lucid dreams and I began experimenting in the with what I could and couldn't do which led me to looking into AP since there are many similarities. Anyway everyone I am out of body and want to get back in I just think of my body and I wake up, that is until I read journeys out of body and tried the laying down back into my body technique instead and when I did this I got a very uncomfortable "click" back in that felt like I have been hit with an electric bolt and I got a weird jolt in the back of my neck with tingling and that nails on a chalkboard feeling. Also an electric buzzing noise.
Needless to say I have not wanted to try to re enter this way again.

Has anyone else experienced this?
