Samwise Gamgee
On their way to Mordor to destroy the One Ring, Frodo Baggins and Samwise Gamgee are led through the marshes by Gollum. They see the aforementioned dead, Gollum stating, "Only shapes to see, perhaps, not to touch." Frodo is mesmerized by the candle-like lights that appear to float over the Marshes (called by Gollum "candles of corpses"); those who are hypnotised by these lights, and who therefore try to touch the bodies, are likely to drown in the waters and join the dead. In the book, Gollum reveals the dangers to Sam, who calls to the stiff and lifeless Frodo and breaks his trance before he can touch the waters.
