fixed it
okay, this is weird. I went into my gmail settings, and then to the filters. Gmail had added two filters to the end of my list....for two friends' email addresses. I couldn't have done it; I didn't know gmail HAD filters. I've never been to the "settings" space. I did manage to delete those two addresses from my gmail filters, but now I'm wondering if I have to check them regularly to make sure they aren't doing it again.
WTF?
