Blocks Glitched Out

I walked into the Mansion and I stopped. When I hit record on the game it didn't show me beginning to move and that made everything glitch out. In the video it has me looking around, I know the area I am in a bit so I walked in a direction towards some of my storage is. And right before I got to the door everything went pink(or blue) and black and I knew that meant like something of a texture issue with minecraft. But then after the blocks and everything in my inventory went back into being their own textures my player skin has disappeared. I tool three screenshots. First one will be inventory, second 3rd person back POV. And the third will be 3rd person front POV. I don't really know what happened to be very honest.
