My roomate in college had a six foot boa constrictor. It lived loose in our dorm room and then in our apartment. Many a time I found in in my bed at night. It was very docile and beautiful.
A boa that size couldn’t hurt an adult, although a much larger python could hurt a young child.
Snakes love you because your body temperature is higher than theirs. When our corn snake got out of her cage, we would find her in the closet burrowed into the sleeping bags.
Nothing wakes you up in the morning like an empty snake cage!
