There is a book called psychic self defense from dion fortune.

witchcraft is hypnosis. ways for planting ideas into subconscious. 

The template of the method is to occupy the rational mind with something - confusion mainly, but fear may be used - to create a hypnotic trance, then insert the payload. Creator of conversational hypnosis milton erickson (which can be considered a witch in that sense) gave his patients a weird handshake that would get them thinking about it, and then come with the suggestions. Thats the origin of the jedi hand of confusion, the purpose of the nested dreams (thats the street theater targeted individuals complain about - freemasons create a chain of stressful false situations around them) in Inception. JK rowling even
described how the masonic square and compass were accidentaly imprinted in her mind and associated with death because she received a call saying her mom died.

And repetition reinforces the idea. While trying to solve the confusion or investigate the subject mentally automatically generates mental repetition (because you have to recall the words repeatedly) 

You know you encountered one of them when you have a set of setences repeating in your head after the encounter. It looks they implanted a 'cloud of tags' i your head. And you recall their conversation you
notice they alternated between praising you and insulting you in a veiled way.

So, as other said, ignore it. But really do. Don't take the baits to enter in trance - when presented with something enigmatic, let it continue enigmatic and see it for the dirty trick it is. Don't try to solve it for curiosity or for the challenge, so you don't enter in trance. And after you hear something which seems shady, forget it immediatly. Don't think about it, really, otherwise repetition will imprint it
in your head. Don't suppose they know something you don't and need to or curiosity will trap you.

Great post. Sounds like a more subtle form of the trauma based programming the spooks and psych community were fucking around with in the MKULTRA days. Trauma + exhaustion + repetition = programming.

We need a Mind Control General to discuss how to recognize and resist stuff like this, or a reading list. I suggest
> Battle for the Mind- Dr. Sargant
> Rape of the Mind - Dr. Meerloo
> Propaganda - Bernays

as mundane starting points.
