3am, in bed and I’m dozing when all of a sudden the inside of my mouth felt wrong.

Alarmed, I instructed my tongue to forage around my teeth, gums and find something familiar to put an end to this nonsense.  But several minutes of tongue mooching brought nothing but further confusion and panic, everything about my mouth felt alien.

As I lay there, considering whether to wake my wife to tell her that my mouth was not mine, without any warning my mouth suddenly became familiar. My mouth was back.  So, thrilled as you can imagine,  I then went to sleep.
