Halloween // Any ideas on celebrating halloween all year round without looking nuts?

Hi I never had the chance to Trick or Treat growing up or enjoy the Halloween festival I belong to a Roman Catholic family and I am from India and my family's take on Halloween is not so positive as they have a typical staunch mindset . But I on the other hand Love Halloween my room is partially halloween decorated and I do a few pranks around to scare people and I remeber My grandparents who passed away and I play halloween music .

But any more ideas to celebrate all year round would really be appreciated .
