Thank you for sharing, @SilverBear! I’ve never tried mirror magic before- but it makes sense that mirrors could be used in a similar way to crystal balls! 
Aside from a few powerful experiences with Deja vu, and the occassional feeling like being an “Old Soul”, I’ve never tried to connect or glimpse into past lives- I’m very curious about this! Have you had much luck with this mirror spell, @christine4? If so- would you maybe willing to share it? I’m quite tempted to give it a try!
