do you recognise the items that were on it? as "Booyah" said in #2 it could be a body bug, a lot of people have been reporting missing corpses, maybe you've discovered where they are going.

So as well as Odin and Thor, Loki is in the game, unbeknownst to us mere mortals, playing tricks with our corpses to freak us the hell out!
