Ok so asleep in bed with OH, 2 children asleep in own bedrooms (baby in with us). Me and OH are woken by the loudest noise almost mechanical sounding and as if its shaking for about 1 minute. When i say loud it was ear splitting loud. I run to check on the children and he runs downstairs (after some encouragement) i look out of the bedroom window at cars and out the other window down into the garden. He comes back up having checked doors and electrical appliances. My heart is beating so fast, we've been lying in bed trying to reimagine the noise and where it came from and how on earth it didnt wake the children! OH has just rolled over to go to sleep but i very much doubt ill be sleeping tonight. It honestly sounded like an earthquake. Now im terrified and trying to rationalise what it could have been!
