Can I "lock" my mirrors?
Yes.
Wash them first, and then you can draw a sigil or even a padlock on the top or bottom corner of your mirrors. (Wash with regular window cleaner)
For sigil prompts it could be like: "this mirror is closed and locked from spirit energy/entry", "this mirror is locked from being a portal." Or whatever wording you would like to use.
Hope this helps.
