For me, this has seldom happened.

From my understanding, we are able to "astral project" or 'remote view" (The Men Who Stare at Goats reference). The thing is, as soon as we start to "analyze" what we are seeing, we are "sucked" back.

One experience I had, I was traversing a series of corridors. Eventually I reached a room. When I entered the room I saw the left (?) side of the room. Up to this point I had simply allowed myself to "travel". When I was in the room, I wanted to see what was on the right (?) side. When I tried to "control" myself to looking at the right side, I was immediately pulled out of it. When I asked my master about it, the analyzing element was explained to me. (I can't remember which was left and which was right)

This concept of "analyzing" what is perceived in meditation, to my current understanding, is essentially the same as becoming aware during lucid dreaming. If you are "over" excited by realising you are dreaming, your excitement ends the dream. Same thing with analyzing.
