A person who lives in a house is aware of all the unswept and unkempt parts of his home, and knows where all the secret things are, but has learned to live with them. For the most part, he cares very much about them, and vows to make them better one day, but for now, settles for things the way they are.
One day, a friend is expected to visit, so he cleans up the house for his guest to see, but generally puts more emphasis on those rooms in which the guest will actually visit. The guest sees what he is supposed to see and gets the impressions he is supposed to get, and then he leaves. For the most part, the guest cares about the person living there and wants the person to succeed at being presentable.
A thief enters the house uninvited and begins to look into the medicine cabinets, the closets, the dresser drawers, under the beds, and other places which are not ready for his inspection, but which get visited, nonetheless. The robber, in looking for something to steal, sees that the person who lives there has hemorrhoids, keeps secrets, hides things under the beds, learns where the person doesn't sweep or mop, and in general, learns a whole lot more about the person who lives there than a normal visitor would. For the most part, he doesn't care about the person living there, except to find that person's secret valuables and steal them.
The Meaning of the Analogy:
People, in their daily lives, allow their minds to become cluttered and disorganized. They mean to do better, but in general, learn to live with their minds they way they are.
When a person talks to you physically, face to face, that person plays the part of the invited visitor. That person sees your mind's persona, its façade, and the personality you want to portray your mind as having. For the most part, the person talking to you wants to see that part of you. They want to deal with that part of your mind and then leave.
When a Remote Viewer enters your mind, or when you, as a Remote Viewer, enter the mind of others, it is as a robber in the night. The purpose of entry may be to simply seek one single fact - maybe plans and intentions for some stock deal or to learn about activities at some specific point in time. But in the process of finding that information, the Remote Viewer often has to look in the medicine cabinets or in the closets of the target person's mind. He sees things which the target person thought were safely put away in mental hiding places. For the most part, the intruding viewer doesn't care about these things, and only cares about what he is there to take. But he sees them.
The point is that when you remote view another person, you should be ready to see and experience some things you may not feel comfortable with (unless you really are a robber). You may find out things about a person you really don't want to know. You may enter, wanting only to visit in that person's mind, but uninvited or not, you can very easily wind up acting the role of the thief.
When that happens, the person can never feel the same about you again. Even if a friend of yours or some acquaintance invites you to remote view them - maybe to see that they are telling you the truth about some certain thing, be careful. You may learn much more about that person than you care to. You may find there some hidden resentment against you that they don't even know about. You may find that the person you like so much is not likeable at all. You may never be able to feel the same way about them again.
The best general rule is to not remote view your friends, relatives, business partners, or other acquaintances, under any circumstances, unless it is absolutely necessary to do so. If you do, just be prepared to be very understanding and forgiving about what you may find in their minds.
Remember, you are there as a thief, not a guest.
