I have been hearing a beep at about 5am (four times now) when early morning messages from one particular person messages me from the UK.
By the timing of the post it is clear the time of my waking and the message beep are synchronous.
My computer (Desktop) is SWITCHED OFF - furthermore I use a switching device to connect TV or DVD or computer. This mornings BEEP came when TV was selected. When I connect ear-phones the sound from my monitor should be directed only to the earphones but I have 'heard' this sound even under these conditions.
What's going on - or is it that I have long-distance telepathy (10,000 miles between us)
