(wait for it; I haven't finished my sentence)
...by electrical hum?
I can't be the only person, can I?
More than once I have had to get up at 3am and go into Smudger's room (at the other end of the landing) to switch the radio off at the plug (it's already off but the switch is on) because I can't concentrate on being asleep otherwise.
I suspect you are going to tell me this is not normal.
But I can hear it I tell you!!!
