Horror movie suggestions?

Try going to YouTube, check out the Short films on the ALTER and Screamfest channels. There may be a few stinkers but by far, many are outstanding and the best part...they are free

Have you seen Get Out and Us? Not quite your typical horror movies but I liked them.

You've probably see already the recent one i saw, The Lighthouse, Us, i think those are best of 2019 for horror. For me i like the horror from the 80's.

I just watched Midsommer... not super scary, but trippy.

Plan 9 from Outer Space, The worst movie ever made, but fun to watch

"The Grudge"

The collector (1st movie)
The Collection (2nd movie)

Not too scary these days, but The Abominable Dr. Phibes is a classic (and fully on youtube). Then again, I like Vincent Price, so take it with a grain of salt.

Oh, if your into slasher flicks, Behind the Mask: The Rise of Leslie Vernon is an awesome take on the whole genre

Dawn of the Dead (the original from 1979)

Terrifier. Terrible movie, honestly, but it's worth it for Art the clown's performance.

A Haunting in CT, not too horror but scary! :)

The Witch
Hereditary

Carpenter's "the Fog" is also recommendable.
