Hello Albeelo: I'm afraid I don't know much of anything with regard to sleep walking. Apparently it is not considered to be a serious condition unless the underlying cause is something serious. In this case, of course, it then becomes a medical condition.

I searched the web for information on this. This website seemed to offer a pretty comprehensive overview of the condition:

Sleepwalking (Somnambulism) Causes & More | Cleveland Clinic

The types of treatments that are typically recommended seem to be similar to those that are recommended for anxiety. It may be best to check in with your doctor.
