I get "Phantom Phone Ringing" if I am suddenly awakened from a slumber.
It is possible that any slight noise that wakens me, I attribute to the Land-line Phone ringing. In my head the sound is identical the the Phone ringing, just once!
It wakes me up, completely!
My Mobile Phone is permanently switched off. (I only use the Land-line).
Every-day sounds which we get used to!
Paul...ringing in my ears...
