Trash Can full of stuff that I didn't delete

have a 2012 mac mini with with macOS Catalina. II went to restore a file that I had just deleted and to my surprise found my trash can full of photos, documents, videos, and other stuff that I did not delete. I really don't think that I could have accidently deleted them due to the diversity of files. I checked about a dozen of them and found that they are also still in their original locations but some are named differently in the trash can. Is my computer automatically moving stuff to the trash? Thanks for your support.
