Villagers sleeping on floor, in walls. Zombies floating.

The attached video will better show what I'm reporting, some villagers have also vanished, there seem to be more glitches every time I log in, starting to near the point of being unplayable.

Wouldn't let me upload my small video (26mb) so I have attached screenshots. The video would have been more useful for you though as the zombies float out one after the other and re hittable.
