Suddenly seeing hidden files

I had an issue with a SSD boot drive a month ago. All is working fine after the use of Disk Utility, but suddenly I saw a bunch of what I assumed were hidden files in the first directory. All sub-folders are normal, but when I open the drive I see a dozen 0kb files that I don't recognize, as well as a few preferences files that I don't believe were there.

Everything showed up on 12/2/2019 at 9:12am.

I tried using a terminal command to hide invisible files, but that doesn't work.

Can I delete these without risk?
