Oblivion quit unexpectedly first. When I went back to the save to try and restart, it said the file was corrupted and I would need to go to a later save. At some point after that I went back to that save and it somehow worked. A couple hours later I went to my house in Skingrad and different characters could be found in chests and added to my inventory. If I removed them from my inventory, the characters would spawn next to me much like dropping an item. Some of the people have names, I even think I had the Gray Prince. Others are Vampire Witch Hunter, Daedra, trolls, horses, and gladiators. The trolls (numerous) are apparently quest items. Sometimes I have numerous characters, even if they are specific people with names. When I went to a save previous to the corrupted one the game is back to normal. Also, all of the items that I put into the chests disappeared, except for example sometimes I would get a random one like Cruelty's Heart necklace and there could even be numerous of them. Has anyone seen anything like this before? I thought It was super abnormal.

No, but I'd suggest to not try and play corrupt Oblivion saves. Because that's obviously what happened.
