EFT is unrelated to head tapping for setting internal wake up calls.
In EFT you're tapping on the end points of the meridian lines to send a kind of "reset pulse" to clear emotional issues. (At least that's the concept.)
To set a "wake up call" you (basicplus2) tap your head with your finger, but probably not on a meridian point, and you're not trying to clear an emotional issue. Also, some people tap their whole head on their pillow instead.
