When I sleep in a bed sometimes instead of the normal “sleeping through the night” screen, the player instead has the same animation as when swimming and the view is just of the floor. The player’s animation is like they keep stopping and starting swimming.
It still skips the night like normal.
It’s only happened to me twice and it doesn’t happen every time but when it does I was in first person.
Playing Bedrock on Android and this happens to me occasionally too. I thought at first it only happened when standing on the bed before pressing use to sleep, but it has occasionally happened without that. Seems random and not connected to blocks either side of the bed, or player position when initiating sleep
