I saw this weird movie as a kid. It is focused on a man who is trapped in a cult and includes a lot of outdoor scenes. I think there might be some invisible dome that keeps people inside. There are lots of people there who have given in to the cult and they do a lot of chanting. There is also some ear piercing sound that the cult members create with their chants which sends the guy mad. The people might also be wearing some uniform. Could have been a TV only thing, no idea.
Invasion of the Body Snatchers (1978)?
The Prisoner (2009)?
I’m not sure how long ago you were a kid, but if you were still a kid ten years ago, maybe you are remembering “Cthulhu.” I honestly don’t remember a lot of details, but I know there was a man who was being intensely recruited by cult members, some of whom were his family members. I believe there was chanting, and lots of outdoor scenes, and eerie ear-hurting noise. I don’t specifically remember a dome.

“The Outer Limits”(1995-2002 TV series)?
There was an episode from the 7th and last season called ‘A New Life’.
There is a cult that’s in an outdoor community and they are surrounded by an invisible wall. It turns out the cult leader is an alien and I think they’re all on a spaceship?
