im still new to keeping snakes aswell and i would highly recoment listening to the people on here there's so much you can learn from them.
please try not to sleep with your snake the risks are so bad. junior my bp managed to get down the back of the leather couch after i took my eyes off him for a minute and needless to say i was in some state (luckily the backs held on with velcro so i got him out ok when i figured this out) just imagine where your snake that you love could get to if he/she decides to move when your asleep. its just a matter of time before it happens
