Well, to add to the confusion: When I go through wall I feel like 'butter', and the walls feel solid, however, I can feel the whole 'through', that is, on a concrete wall I can feel the little pebbles in it, and the limey smell, etc- even a sense of temp., but when I go through water, it feels like nothing- imagine going through a hologram- you see it in 3-D but it has no sensation whatsoever. That's how it has been for me. I wouldn't know it was there if I couldn't see it.
