I don't have enough information to say exactly who Anthony Krueger is in this story. He could be an ordinary person with an extraordinary story, or perhaps he has a special role in a particular community or field.
Freddy Krueger's story goes like this. He was a child murderer who was burned alive by the parents of his victims. Now, as a supernatural entity, he seeks revenge by entering people's dreams and causing their deaths.
Definitely not. Freddy Krueger is purely a creation of imagination for the purpose of scaring and entertaining in the realm of horror fiction. There's no real-life basis for such a character or the events associated with him.
Freddy Krueger is a horror icon known for terrorizing people in their dreams. He was a serial killer in life and gained the ability to haunt and kill in the dream world after his death.
He could fall in love with a fellow dream entity. Maybe there's a beautiful and mysterious being in the dream world who catches his eye. This being could be like him, having some power over dreams, and they start to bond over their shared abilities.
