Strix

Strix is a film from 2021 that stars Tiffany Skye Goldermann. It takes place in 1977 and involves people who are vanishing.

This might be why they're vanishing. Tiffany gets abducted by a coven of witches and is suspended barefoot from the ceiling.

I haven't seen the film, beyond this clip by Jakob 88, which you can see right here.
