It's a bit exagerated, you may try the trance exercise to understand. I admit never doing it but I understood I am more in a receptive state.
But let's admit you can psychically contact people in this state :
If a voice talk to you in your head and command something, you can doubt this though really comes from you, it's disturbing.
I had this problem long time ago, some disgusting injonction asking on an imperative tone to be insulting and I fought against that. Surely the same enemies schizophrenics must confront.
If an entity clings to your aura in order to control you, it must subtly suggest this or that so you progressively get used to its presence, until you identify yourself to it and become incapable to distinguish its tone from your.
What a patient way to go ! and there is many cases like this in psychiatric hospitals.
So to command someone, this person must not be vigilant (mentally immature or in hypnosys state) and you must be able to astrally talking in his head.
The context itself is disturbing and insane, it should be easier and naive with an animal.
That aside, transmit data to others is interesting, and if they are able to understand it comes from you, it's great.
