Thank you so much for your post. I'm glad to hear that your sister is doing well, that age is so difficult to begin with, and a lot of people battle the same issues- maybe that's why such phenomena are more prevalent in females around that age. Both times, whatever the reason, she had a concrete reality to go along with what she experienced.
From what I've read, there is often the same kind of reality that goes along with OBE and NDE. There is so much in the world that we simply can't explain. Thank you again for sharing your story. Sounds like your Mom had a pretty smart idea, with a pretty amazing result.
G-d ♡ bless you!
