It sounds as though he may just have been sleeping out in the open due to the heat, as long as he's fine now it doesn't seem like a health issue, just keep the room as cool as you can while the heat continues & keep an eye on him for any other signs just in case there is something wrong.
I've never heard of hams having epilepsy, they can have strokes but then there would be after effects so this does just sound more like a heat issue.
