There is some bug with Textures and my minecraft multiplayer

So i was in my house doing some upgrading and putting stuff in my chest until
i seemed to notice that my BED textures were not right and all messes up, because i have been playing this game for idk like probly started around 2010 and i KNOW that the bed textures are suppose to look right! And i also noticed the doors had messed up too.... Please look at the screen shots below and please tell me how i can solve (not connecting to multiplayer servers) (messed up textures) (looks like when i fall the ground seems to break and peices fly everywhere) Screenshots attached.
