Care to take part in a "locked" room mystery?

This morning, I took a shower as usual, turned the fan on and the light out when I left and closed the door.

Now we can’t open the bathroom door. I did not push the lock button. (I know this, because when these doors are locked, the handle won’t turn.)

The handle turns on the bathroom door, but nothing happens. My husband put his shoulder to the door, but nothing happened then either.

The hinges are on the inside of the door.

I am crossing my tentacles. How do we get this open?
