I expected no sound to be played while standing still on a bed someone was sleeping in it.

While standing on the 'head side' of the bed with someone sleeping in it, then it constantly played the stepping on wood sound for the person sleeping, and a walking sound for the person standing is played depending on the blocke next to the bed. I have explained it all in a short video here http://youtu.be/mEeCk397DrM.

Steps to Reproduce:
1. Place bed
2. (optional) Place any block into the 'pillow side' of the bed.
3. someone sleep in the bed.
4. Another player stands on the pillow side of the bed, while the first player is sleeping. Now listen.
