  • Yes, I do. And my snakes do, too. Ever since they fracked here in the UK, and since I moved to a 4th floor flat, plus been bedridden, I notice them far more. They are more noticable lying down, I can't feel them standing up. The snakes will even come out of hibernation if the quake is close(the bristol channel quake was minor, but large for the UK, and it had me and the snakes up 13 hours beforehand, only fb let me know there was a quake, and after, the snakes went back to sleep, and so did I. There were only 7 volcanoes going off then. Snakes lie down all the time, and they are deaf, but sense vibrations as well as heat to hunt. So are very sensitive to tremors. A book called when snakes awake was published when I was born, 1975,But I found out after I solve the mystery by keeping snakes for 30 years.
