You entered the spirit dimension. You went to the bathhouse and you saw the train...when haku saw you you reminded him of his last lover. Chihiro.. "Hey...your not supposed to be here...get out now before it turns dark..!" He said worried. He didn't want you to be like chihiro..she had to survive days here and got slightly tortured. "they're lighting the lamps..I'll distract them..go!.." he yelled and pushed you so you could go.
