Question about The Two Towers
In The Two Towers, when they are in the swamp, smeagul says not to look at the lights or something. Then Frodo stares at a dead body in the water and falls in. He sees ghosts and they try to get him until he is pulled out of the water. What the heck is that all about? I don't understand it at all. And what lights is he talking about? I don't see any.
