Yep! Dead people spirits! Well... when a spirit medium-- that's what I am-- channels a spirit, her own spirit is dormant while the spirit they're channeling takes over. Their appearance changes to that of the person they're channeling, besides hair and clothes. I don't even know what's happening while channeling!

So, if you ever see someone walking around with my hair and clothes but not my face or body, you'll know it's a spirit!
