Stuck in bed, alone, forever, SAD

-While on single player and not open to LAN, I went to "sleep" on Creative mode. I had just teleported to near bed from a significant distance.
-Went dark and became day, like it's supposed to, but it would not allow me to leave the bed, though the Leave Bed dialogue and command line were there.
-While in the bed I was still able to write in the command line, but could not leave bed. I was able to change my game mode and teleport but when I would click Leave Bed, it would put me back on the bed, without dismissing the Leave Bed dialogue.
-I had to kill Minecraft entirely and restart.
