What I expected to happen was...:
Villagers will either pick up items without moving or not pick up at all

What actually happened was...:
Villagers moved around the bed in a weird way, while lying

Steps to Reproduce:
1. Breed some villagers (i dont know if necessary)
2. wait until one of them goes to sleep. Works better if few beds are near each other
3. Drop some food items that villagers normally pick up
