Let's see, if a ghost or another form of a deceased person approached you, how would you know unless the spirit told you? How would you react to such information? You may just assume you're dreaming and you'll soon awaken. This draws your attention to different illusory levels of thinking and resulting experiences. After all, how do you perceive and ground your reality? What are the sources of these beliefs?

Many people compare what they think they know with what people have told them. Separating internal from external perception can seem quite tricky, if you don't buy into the idea that you project what you choose to perceive. Some people never learn to distinguish dreams from reality. Others believe these are one in the same.

Spirits appear when its helpful to them and to us for them to do so. We don't always have to know, though you may sense as much even if you're told nothing of the sort. You are always in the right place at the right time, although you may believe that's a matter of interpretation. Ghost encounters happen all the time, even near you.

Consider how you take what you already believe and consciously or unconsciously impose it on others. When a stranger appears in your life and challenges you to rise to his level, why would you keep attempting to bring him down to your own?

Not knowing the essence or true identity of a spirit may also mean not giving yourself the chance to be jaded by fear. As such, you would likely perceive ghosts as you would anyone, through the filter of your illusory belief and self-understanding.
