They may become aggressive and coil tightly around a person. This will cut off the air supply. It isn’t a good idea to allow them to roam around your home while you are sleeping.

They may bite if they are spooked but they aren’t that dangerous in that regard. They will hiss when they are agitated and that is a sign that they may strike. The wound should be looked at by a doctor though due to infection being possible. Should such an infection spread it could cause permanent damages internally.
