Question: Whenever Freddy emerges from Jesse in the real world, why doesn't he have his glove on? Why are his blades coming out of his fingers?
Question: What was up with the coach's death? Was Freddy trying to rape him or something?
Answer: I think the coach's death was a play on his character being at a S&M bar. People who frequent those places are usually into bondage and being dominated. Hence being tied up, and whipped with the towel. It also fits in with the homoerotic subtext throughout the movie.
Answer: He's a dream demon and uses his powers to torment Jesse in any way he could, including having claws or even Freddy himself burst out of Jesse.
