You may not be able to move if they are on top of you. I wake up a couple times each night because of my cat. Anyway, as you can see from these pictures, this woman likes to cuddle up with her pet python.
I have never been much of a reptile lover and cannot image sleeping with one! She lets her python stretch out along her body from head to toe. Other times it encircles her. Suddenly, the python stopped eating. As a concerned pet owner, she took it to the vet.
