Um...never seen or heard of one...but it sounds like someone is using something from their own mind to activate the minds of others...or something like that.
Number one...Anyone can block any kind of influence sent by others. It just takes awarness and practice. Awarness that we can...and practice with our own minds, doing our own things. And practice may not be necessary if we are aware.
Number two: If we look at TV we are receiving influences constantly. We can't help but pick up the intentions of anyone broadcasting anything...just the same as 'falling in with bad companions'...or 'good' companions.
Personally, I wouldn't intentionally plant the thought with my child that another is going to influence them...there's enough of that in churches, and on TV, already.
