Dean threw away his necklace for a number of reasons. 1: he thought it was useless. 2: he was angry with sam, and 3: he sort of lost hope and did not believe anymore.
Protection Amulet
Sam and Dean Winchester.
Sam and Dean's father is named John Winchester.
Dean Winchester's necklace, a christmas present from his brother, was meant for his father to 'protect him'. We later find out that it's believed to be a tool to find God. Although, since he was never found, its unknown if the necklace actually works.
The subconscious associates Sam and Dean from Supernatural as someone who can help in a terrifying situation (aka nightmare). Also their likely infatuation with either of the "Winchesters" is a factor.
Dean always wears a Egyptian Protection Amulet. It's a head with ram horns. In the episode 'A very supernatural Christmas' it shows us how he gets it. You can buy a replica of Ebay and also get a closer look at it.
Dean and Sam's car in "Supernatural" was a 1967 Chevy Impala. =)
