Often it is said you must empty your mind or reduce it of noise to make remote viewing work.
We do have a mind or even various minds and we also have the ability to know and control them, if you know them.
Ability to control pictures and mental masses is an individual thing and we are lucky to have some techniques to play with, handle or remove them.
A Clear or OT I would perceive to be more or very reliable in their remote viewing sessions.
It is often stated there are natural psi proponents but I am more inclinded to see them as 'in charge of their own minds' or perhaps Clear and OT.
Here is a brief lesson on remote viewing from who I consider the originator of the Science.
Note that he also has a Scientology background:

“Within the contexts of that research, neither meaning nor mental images come first.
Rather, signals come first, then meanings of them, and then mental images based on the meanings.
Within the scope of the human nervous systems, signals in-put via any of the sensory detectors are electronic in nature.
The electronic signals are then decoded, via pre-conscious processes, into meaning categories and specifics, and it is the results of this decoding that, in turn, trigger on mental perception of them.
Save to say that signals ARE somehow translated (transduced) into pre-conscious meaning, and then into mental awareness and perception, no one yet exactly knows how any of this takes place.
For clarity, three steps are involved here:
(1) Signal in-put;
(2) Meaning comparison within the contexts of meanings already stored in memory;
(3) Mental perceptions (feelings, images) built upon the meanings.
In any event, within the contexts of RV research at SRI, it turned out that meaning (of things and situations) was the fulcrum of functioning BETWEEN signal in-put and mental images of them.
This is to say that remote viewing does not begin with mental perceptions, whether in the form of feelings or images that are propelled into the state of conscious awareness of them.
Rather, these are the end products of the two preceding steps, both of which are contained in functions that are pre-conscious beneath conscious awareness of them.”
