You are suffering from something we refer to as a PARASOMNIA...that s a sleep disorder. In order to get better information as to what may be causing this type of behavior both a physical examination, labs, and sleep study are recommended, preferably by a neurologist or sleep specialist. Sometimes medications or changes in medications can cause this sort of thing and other times there is no clear cut cause.
