1) ... being in a deep hole with no one around, and no way out.
2)... being a child lost in a big city, looking up only to see giant buildings, and the blue of the sky.
2)... being in a big, scary forest.
4) ...the feeling I imagine Alice had when she fell into the hole.
5) ... what I imagine an ant must feel when he's travelling through the grass.
6) ... feeling scared my life has no direction, and trying to find a way out.
