Jack the Ripper is a good guess, but personally I think it's about Freddy Krueger.
Reason I think so is because sandmen bring sleep and dreams, right? Freddy Krueger kills his victems in their dreams, like a blood red sandman.
Second reason is the part about the children weeping, Freddy Krueger, before he was killed, was a child molester. Now whenever he is in his victem's dreams, the children sing that creepy song about him.
Last reason is that Freddy can do anything in the dream world, like bringing flames or cold.
