Being a demon at his core, Sebastian isn't the one who can be of any help concerning Astre's nightmares, being during his entire time of serving him, Sebastian entire existence and his ties to the contract was one of the reasons why his nightmare kept recurring.

It wouldn't make him any more appetizing. Souls are what they ate for one lifetime and he'll be damned if Astre tastes like instant ramen noodles or like greasy foods available, so the demon would be equally appalled but for a different reason.

"I'll check the rest of the house." Before Astre went up the stairs. "You'll be all right. The lights are on now and the staff are not monsters. They're the residents of the valley who wears makeup and costume, so that was all." As Sebastian is confident with the lights on, no one gets lost. "If you get lost, just come back downstairs and meet me and wait for me in the lobby."
