Looking for good older horror films like the shining or burnt offerings have a lot of horror films but looking for new ideas that I haven't thought of... your suggestions helpful

Have you see "the thing"

The Thing (1982)

I love that movie. Makes my skin crawl every single time. Also filmed very well.

Have you seen the original "Wicker Man," from 1973?
