first of all that dead girl and apparently the dead body there is not so it could be why she was not moving. when was she last woken up (6:11 in this video). if it was so hot it jumped on the site it could have fallen on the site of I think her body there cause her skin is so thin she is forced to perch on dumb bc she couldn't do anything him stood like 6 inches and you can see him stand on top of the dead girl.
