So at night time / early morning I sometimes hear what I can only describe as a noise that sounds like the sound you would get if you were to run your fingers over a few letters on your phone / iPad -like a high pitch clicking noise. Sometimes it's around 3/4 'clicks' that are always close together sometimes there Might a tiny pause and then another few clicks sound. But they always have the same fast rhythm.
It happens when we are all in bed, making no movements so it's not like we are walking around and it's making the floor shake at all.
Can any one help with any suggestions on what on earth it might be!
I've been hearing it now for a few months,
