How about getting him a Blu-ray box set or DVD of his favorite horror movie franchises or a horror movie he's been meaning to watch? You could pair it with some spooky snacks like popcorn coated in Halloween-themed seasoning or a gummy candy shaped like a brain. Another idea could be to book a horror-themed escape room experience or haunted house tour for the two of you to enjoy together. Or, if he likes to read, you could get him a horror novel by his favorite author or a subscription to a horror book club.
Or you can get him a star map with an important date you share.
